(You can "peek" at part of the answer next time by pressing the space bar if you'd like.) end read Press the ─┘ key to continue to next section..... return -opt6 -line503 %i = 600 -line600 %H = "How to print" | call -header| begtype The simplest thing to for Extended Batch Language to do is to print text on the display. This is done by either of two commands, TYPE and BEGTYPE. The TYPE command can be used for something as simple as saying hello! For example: BAT TYPE HELLO THERE This is all that is needed. This command can be typed directly from DOS (this is called immediate mode) or be entered into a file such as "TRIAL.BAT" (this is called direct execution mode). To execute it as a BAT program with the file, just type the file's name "TRIAL" from DOS and you will see the results of the program "HELLO THERE" coming from BAT. end goto -scroll -line601 call -header | begtype You can also put DOS variables into this command to display their contents. For example, if the "TRIAL.BAT" file contained the line: BAT TYPE HELLO THERE %1 %2 Then when we start the BAT program from DOS, we might enter: TRIAL COMPUTER USER DOS will automatically store the words after the program name into its variables. Therefore, in the TYPE command, we will see contents of these variables on the screen. The resulting message would be: HELLO THERE COMPUTER USER end goto -scroll -line602 call -header | begtype There is a second method of putting text onto the display. This is with the BEGTYPE command. Although it will not display the contents of variables, it is very useful for displaying large blocks of text, such as menus. For example, if the "TRIAL.BAT" file contains: BAT BEGTYPE This is a large block of text. It is useful for menus. Note that Upper/Lower case characters are displayed intact here. The block is always ended with "END" in the first column after the text finishes. END When executed, the "TRIAL.BAT" program will display: This is a large block of text. It is useful for menus. Note that Upper/Lower case characters are displayed intact here. The block is always ended with "END" in the first column after the text finishes. end goto -scroll -line699 %i = 603 -line603 call -header | begtype There is an additional advantage to using BEGTYPE command. This command can also highlight text to the user. This is done by using the form: [\\hex] within the text block. For example if the text block contained \\0F within the text, the result would be \0F High Intensity Text ! \07. By choosing different values, the screen attributes can be controlled to create inverted video, blinking, underlined, and very colorful text. You can also display the contents of variables by using [\\%Var.name] in the text block. For instance, if the variable %0 is to be printed, use \\%0 within the text after the BEGTYPE command. An additional command CLS can be used to clear the display before printing data. For instance, the combination "BAT CLS BEGTYPE" is quite useful for printing menus and text such as this screen. end goto -scroll -line604 begtype \0fNOW IT'S YOUR TURN !!!\07 If the \0f%4\07 variable contains the word \0fDAY\07, what is the command to display the words "\0fFUN DAY\07" on the display? end %A = "BAT TYPE FUN %4" | Call -tryit -opt7 -line605 %i = 700 -line700 %H = "Reading things from user" | call -header | begtype In order to get input from the user, there are two available commands, READ and INKEY. When the command word READ is seen in the batch file, an input line is accepted from the user. All function keys are assigned to the normal DOS edit functions. When ENTER is pressed, the input line is assigned to DOS variables. Each word will be assigned in order to the variables indicated after the READ command. When there are no more variables after the READ command to assign, the remainder of the response is thrown away. If there are more variables to be assigned after the READ command than there are words from the user, these variables will be cleared out to a empty state. For example: BAT READ Please enter your name ==> %1 %2 This would prompt the user and wait for him to enter two words. These words will be saved in the %1 and %2 variables. end goto -scroll -line701 call -header | begtype Note that there does not have to be any variables indicated after the command READ. In this case, BAT would wait for the enter key, throw away any response, then continue to process the next batch file command. end goto -scroll -line702 call -header | begtype In the event that you wish to get a single keystroke from the user, the INKEY command should be used. This command will wait for the user to enter a single key on the keyboard and return its value in the optional variable. This key can be not only letters, but all function keys, control keys, etc. For example: BAT INKEY Press any key to continue... %0 When the user presses a single key, that key is saved into the variable %0. If the key that is pressed is in the range of "!" to "z" (decimal 33 to 122) then the key saved to the optional variable. If you wish this key to be echoed to the display, you must specifically use the TYPE command. end goto -scroll -line799 %i = 703 -line703 call -header | begtype If the key is not in the above range, then the key will be converted to the form "KEYxxx" where xxx is the hex value of the key. Extended key codes will be in the range KEY100 to KEY1FF and nonextended key codes will be in the range KEY000 to KEY0FF. Refer to Appendix G of the Basic manual for a complete description of the various assignments of key codes. The character does not have to be assigned to a variable. If the variable name is not present following the command INKEY, the system will wait for any key to be pressed from the user, and then continue processing. end goto -scroll -line704 begtype \0fNOW IT'S YOUR TURN !!!\07 We wish to create a menu with several options. At a "\0f=>\07" prompt, the user must enter a \0fsingle letter\07 to select his option. What is the command needed to request a single keystroke into the \0f%4\07 variable for option selection using the prompt above? end %A = "BAT INKEY => %4" | call -tryit -opt8 %i = 800 -line800 %H = "Program Control" | call -header| begtype There are several ways of controlling the order of execution of a program written with Extended Batch Language. GOTO, CALL, RETURN, and IF are all commands that do this. The simplest is the GOTO command: BAT GOTO -LABEL If this line is put into a ".BAT" file, then it will stop execution at this line and resume at the line within the file which contains: BAT -LABEL This is a unconditional branch. If the label is not present within the file, and error will result. Note the minus (-) sign before the label name. \0FLabels must be preceded with a minus sign.\07 This is done so that BAT can tell the difference between a label and a command within the language. end goto -scroll -line801 call -header | begtype A CALL command is similar to a GOTO command. The primary difference is that the line where the CALL command was is saved away. Then a branch to a label is done, just like the GOTO command. Note that the CALL command can be nested up to 31 levels. When a RETURN command is found, the last line that was saved is now restored. Execution resumes at the line following the original CALL command. end goto -scroll -line802 call -header | begtype For example, if a program contains: BAT TYPE One BAT \0FCALL -LABEL\07 BAT \0FCALL -LABEL\07 BAT TYPE Four BAT EXIT BAT -LABEL BAT TYPE Two BAT TYPE Three BAT \0FRETURN\07 You will see on the display: One Two Three Two Three Four end goto -scroll -line803 call -header | begtype The final way to control the flow of an Extended Batch Language program is to use an IF command. The general form of this command is: BAT IF _word_ _condition_ _word_ _operation_______ Each word can be a fixed string of letters, or a variable, or a combination of each. The conditions can be: < less than > greater than <> not equal to = equal to (case insensitive) == exactly equal to (case sensitive) The operation can be any of the Extended Batch Language commands. end goto -scroll -line899 %i = 804 -line804 call -header | begtype For example, all of the following IF statements will compare correctly and execute their corresponding TYPE command. The first two statements will initialize variables used in the IF commands. BAT %1 = ABC BAT %2 = BAT IF ABC = %1 TYPE The variable contains ABC. BAT IF %1 = abc TYPE This also matches. BAT IF 0 <> 00 TYPE These are different lengths. BAT IF 0 < 00 TYPE 0 has a smaller length. BAT IF 456 > 123 TYPE Numerically, 456 is bigger. BAT IF 456 < %1 TYPE ASCII value of 456 is smaller. BAT IF AABCD = A%1D TYPE Token substitutions are made. BAT IF %2 <> %1 TYPE Variables are different lengths. BAT IF .%2 = . TYPE This matches if var is empty. BAT IF BOX = BOX IF DOG <> CAT TYPE Did multi-if compare. BAT IF 1 + 2 = 3 TYPE Arithmetic results match. end goto -scroll -line805 begtype \0fNOW IT'S YOUR TURN !!!\07 We wish to make a series of tests on a menu option that a user entered. It is saved in the variable \0f%4\07. What command is needed to test for the letter "\0fA\07"? end %A = "BAT IF %4 = A" | call -tryit -opt9 %i = 900 -line900 %H = "KEYBOARD STACK" | call -header| begtype There is a method within the BAT language for answering questions from programs without operator intervention. This is done by a "keyboard stack". By entering data into the stack, you will essentially be entering data through your keyboard when any program requests it. In this way, a batch file can now answer questions programs may have by 'typing' them for the user. The keyboard stack operates in a "first-in first-out" basis. That is, the first line of text put into the stack will be the first seen by the program when it reads the keyboard. The second line entered will be the second seen by the program, and so on. As long as there is text remaining on the stack, ALL requests for data from the keyboard will actually come from the stack. Once the stack has been emptied by the program, data will then come from the keyboard as usual. There are two commands which store data into the stack, STACK and BEGSTACK. Here's some more about them..... end goto -scroll -line901 call -header | begtype The STACK command is very much like the previously mentioned TYPE command. Instead of displaying to the screen, it will "push" data into the keyboard stack area. When any program is ready to accept information from the keyboard, the parameters after the STACK command will be used as input. For example: BAT * This program will issue remarks to DOS. BAT %1 = HELLO BAT STACK REM THIS IS A REMARK FOR DOS BAT STACK REM VARIABLE %%1 = %1 When executed, the following will appear on the screen: A>REM THIS IS A REMARK FOR DOS A>REM VARIABLE %1 = HELLO end goto -scroll -line902 call -header | begtype The second command used to stack data is BEGSTACK. This command is equivalent to BEGTYPE previously described. It is useful for dumping large amounts of data to the stack area. Although no parameter substitution is performed, there are several advantages to its use. First, if a line ends with the ";" (semicolon) character, a carriage return will NOT be stacked. Second, if "\\HEX" is used where HEX is a number from 01 to FE, then this exact keyboard value will be stacked. This is useful for stacking special control characters and symbols. Third, if "\\00\\HEX" is used, an extended key code will be stacked. This is useful for stacking function keys and the like. Refer to the Basic manual in Appendix G under "Extended Codes". Fourth, if \\FF\\HEX is used, the stack will delay the keyboard characters from appearing to the program for HEX number of CPU "ticks". There are about 12 hex (18 decimal) ticks per second in the CPU. In all cases, the word HEX above represents a two digit hexadecimal number. Finally, \\\\ can be used to stack a single backslash. Some examples... end goto -scroll -line903 call -header | begtype Some examples of BEGSTACK command:: BAT BEGSTACK \\09 Will stack the tab key. This text will be stacked ; on one line! \\00\\3B Will stack an F1 key. \\\\ is seen as one backslash. \\FF\\24 will pause two seconds. end Hint: Some programs remove keystrokes before accepting a critical key. In some cases this can be avoided by using \\FF\\01 in the BEGSTACK command. end goto -scroll -line904 call -header | begtype Note that in the above examples, the STACK or BEGSTACK commands always are \0fbefore\07 the command or program that will be using the keystrokes. An example of this order is: BAT BEGSTACK <<keystroke values needed by the program>> END <<program that will be controlled by the stack>> An example of using the stack with the COPY command within DOS would be: BAT BEGSTACK This text will be given to the copy command. \\00\\3B An F1 key ends the copy. END COPY CON: result.txt end goto -scroll -line905 call -header | begtype There are also three control commands which are associated with the stack: STACK.OFF - Redirects data to come directly from the physical keyboard. Does not remove any data in the stack. STACK.ON - Directs data to come from the stack. This is the default. STACK.PURGE - Removes any data from the stack and keyboard buffers which are pending. end goto -scroll -line999 %i = 906 -line906 begtype \0fNOW IT'S YOUR TURN !!!\07 From our menu, we wish to start up a communications program and automatically dial a phone number with a smartmodem. The communications program we have will take what is typed on the keyboard and send it to the modem. The command needed for the modem to dial our phone is "\0fATD12\07" . What Extended Batch Language command will force the communication program to dial this modem command? end %A = "BAT STACK ATD12" | call -tryit -opt10 %i = 1000 -line1000 %H = "GETTING RESULTS!" | call -header | begtype The results of programs often need to be known so that some action can take place after the program ends. When the command word READSCRN is seen in the batch file, a line of text is read from the display screen into variables. Having the ability to read text from the display can be useful for determining the result of another program, or making a query for some system status which would not normally be available within a batch file. For example, by reading a directory from the screen, a series of files can be submitted to the macro assembler. Once the assembly is completed, the status can be read from the screen to determine if there were errors which would stop the link step. Virtually any message which a program can generate can be used as feedback to a batch file by using READSCRN. end goto -scroll -line1001 call -header | begtype Its operation is very much like the READ command except for the fact that the information which is being read is coming from the display screen and not the keyboard. Like the READ command, the text from the screen is tokenized (separated at word boundaries and assigned to variables). The return code %R will be reflect the line number on the display that was read. This number will be in the range of 1 to 25 for the top to bottom lines respectively. Once a line is read, this command will be set to read the previous line. Repeated READSCRN commands will read UP the display! For example: BAT CLS BAT TYPE HELLO THERE BAT READSCRN %A %B %C After execution: %A contains HELLO %B contains THERE %C contains nothing, it is empty. %R (return code) contains 1, the line number that was read. end goto -scroll -line1099 %i = 1002 -line1002 begtype \0fNOW IT'S YOUR TURN !!!\07 From our menu, we have started the IBM Macro Assembler program. We know that when this program ends, it will display a number representing the number of errors that were found. We want to make sure that this number is zero before continuing to the LINK program. If we save this number in the variable \0f%A\07, what is the command to read the assembler result from the display? end %A = "BAT READSCRN %A" | call -tryit -opt11 %i = 1100 -line1100 %H = ASSIGNMENTS | call -header| begtype If the first character in the command is a '%' (Percent sign), then it is considered to be an assignment statement. The first variable cannot be any predefined variable (such as %R or %%), but may be any of the other variables %0 to %9 and %A to %O. If a DOS command is later executed and uses one of the variables %0 to %9, it will be properly replaced with the contents of that variable. The first assignment token, the operator, and the final tokens are optional. The assignment statement must appear in one of the following forms: \0f[var] = \07- create empty variable \0f[var] = [string] \07- simple assignment \0f[var] = [number] + [number] \07- addition \0f[var] = [number] - [number] \07- subtraction \0f[var] = [number] * [number] \07- multiplication \0f[var] = [number] / [number] \07- division \0f[var] = [string] # \07- string length \0f[var] = [string] $ [index] [length] \07- create substring (like MID$ in BASIC) end goto -scroll -line1199 %i = 1101 -line1101 call -header | begtype \0f[var]\07 - A DOS variable or global user variable %0 to %9 and %A to %O. It may not be a predefined variable. \0f[string]\07 - Any valid token. Letters, numbers, any variable, or any combination there of. 123, ABC, and 987%J4SF are all valid strings. \0f[number]\07 - Any token with a numeric result in the range of ± 2**64. For example (if %A contains 34) the three numbers 98, %A, and 12%A5 (equivalent to 12345) would all be valid numbers. \0f[index]\07 - Same restrictions as [number] above except that an [index] above 16 is meaningless and is equivalent to the number 16. \0f[length]\07 - Same restrictions as [number] above except that a [length] above 15 is meaningless and is equivalent to the number 15. Note that [length] is optional and has a default value of 15. end goto -scroll -line1102 begtype \0fNOW IT'S YOUR TURN !!!\07 We wish to count the number of times that a user has used a certain .BAT program. We will keep this count in the global user variable \0f%A\07 which will stay active even BETWEEN batch file execution. What is the command needed to increase the value in this variable by one? end %A = "BAT %A = %A + 1" | call -tryit -opt12 -line1103 -line1299 %i = 1200 -line1200 %H = "DEBUGGING AIDS" | call -header| begtype As an aid in debugging, the TRACE.ON command enables a trace flag which causes each line in the BAT program to be printed as it is executed. Three '+' (plus) symbols will precede the BAT statement which is printed out as an aid. The trace can be turned off at any time by the TRACE.OFF command. A trace can be active during DOS commands within the BAT program. In addition, trace can be enabled/disabled at any time, even in immediate mode. Once enabled, it will remain in effect until the TRACE.OFF command is executed. Errors, execution of other BAT language files, and even executing DOS commands will not change the trace mode. end goto -scroll -opt13 -line1201 %i = 1300 -line1300 %H = "External Functions" | call -header| begtype External functions give Extended Batch Language additional capabilities. They are programs that add new commands within the EBL language. Within these external functions are helpful routines in writing complex EBL programs. Generally, you will be able to write almost all of your EBL programs without these functions. Occationally there may be some special need for a unique operation that is not part of the commands built into Extended Batch Language. This set of external functions can therefore be added to EBL as needed. To use any of these functions, just enter the name of the external function package from DOS or put the name of the package within your AUTOEXEC.BAT file. Your batch files can then have any of the additional capabilities that are contained within the function package. end goto -scroll -line1301 call -header | begtype \0eProvided to non-commercial users to share and copy:\07 \0fBATFUNC1\07 contains CENTER, CHDIR, DATE, GETDIR, KEYPRESSED, LEFT, LOWER, LOCATE, RIGHT, STRIP, TIME, UPPER, WHATFUNC \0eProvided to registered users only:\07 \0fBATFUNC2\07 contains C2H, D2H, H2C, H2D, INT86, PEEK, POKE, REBOOT, WHATFUNC \0fBATMATH3\07 contains FLOAT, ABS, FRAC, INT, WHATFUNC \0fBATALLF\07 contains all of above functions within one package. \0fBATXV\07 contains Extended Variables. Allows almost unlimited variable space. Also allows flexable variable names, indexing, and array capabilities. Source code to all external functions is also provided to all registered users. end goto -scroll -line1302 call -header | begtype A summary of the commands provided within BATFUNC1.COM are: CENTER( string i [pad] ) - Centers a 'string' within an 'i' field CHDIR directory - Changes sub-directory to 'directory' DATE() - Returns the system date GETDIR() - Returns the current subdirectory KEYPRESSED() - Returns "T" if any key is pressed LEFT( string i [pad] ) - Left justifies 'string' within 'i' field LOWER( string ) - Returns 'string' in lower case LOCATE x y - Move cursor to new position x y RIGHT( string i [pad] ) - Right justifies 'string' within 'i' field STRIP( string [type [char]] ) - Removes blanks or 'char' from 'string' TIME() - Returns the system time UPPER( string ) - Returns 'string' in upper case WHATFUNC() - Returns the names of the functions loaded Complete details of each function, including examples, can be found in the Extended Batch Language Version 3 Users Guide starting on page 163. end goto -scroll -line1399 %i = 1303 -line1303 call -header | begtype These functions can be used any place a variable or other values can be used. For instance, they can be used in an expression: BAT %A = LEFT( %B 8 ) They can be used in a condition statement: BAT IF KEYPRESSED() = T THEN GOTO -HAD.KEY Or they can be used in combination with each other: BAT TYPE The hour is now: LEFT( TIME() 2 ) In general, external functions can be very powerful additions to Extended Batch Language. Registered users receive details of how to add their own custom additions using external functions. The BAT-BBS will be the repository for all new functions from other users. end goto -scroll -opt14 -line1304 %i = 1400 -line1400 %H = "Additional Information" | call -header| begtype The size of the keyboard stack defaults to 1024 bytes. This value can be changed by making the first statement which is executed by the Extended Batch Language program be of the form: BAT * size. Size is the decimal number of bytes to reserve for the stack. This must be executed, for instance, when a system reset is performed because once this area is installed, the size is never altered until another system reset. There are additional variables %A thru %O (oh) which are called "global user variables". These variables are used exactly like the variables supplied by DOS (%0 to %9) with two exceptions. First, the contents of these variables are maintained between execution of batch files for as long as the system is powered on. This "global" feature is useful for keeping indicators BETWEEN "sessions" of the user. Second, because DOS does not know about these variables, they \0fcannot\07 be used as variables within any DOS command. So while "COPY %1 %2" is valid, "COPY %A %B" is not. If you wish to use them within DOS commands, they must first be copied via a statement like "BAT %1 = %A". end goto -scroll -line1401 call -header | begtype PREDEFINED VARIABLES... A return code is available at memory address [0000:04FE]. If set by a program, BAT can read this byte value with the variable %R. The string stored into this variable is in hex with leading zeros truncated. The current default drive is stored into the %V variable. It is a single character. The status of the stack is stored into the %Q variable. It is a "K" if the READ command will be reading from the keyboard, and a "S" if it will be reading from the stack area. There are two character literals. %S represents a space literal and %% represents a percent sign. Either of these special variables can be stored into other variables, or used for testing special cases. end goto -scroll -line1402 call -header | begtype The STATEOF command will search all disk drives for the existence of a file. The name after the word STATEOF can be a specific name, general name with wildcard characters (e.g. *.EXE), or it can be a name with a specific drive specification (e.g. A:PE.EXE). In the last case, only drive A: will be searched instead of all available drives. Note also that a variable can be used instead of a file name. In this version of BAT, only files in the current directory (no paths) can be found. The return code variable %R is used to indicate the result of the search for STATEOF. The results are: 0 - File found on default drive. 1 - File not found. 9 - Invalid file name specified. A to D - Same as return code 0 but instead of being found on the default drive, it was found on drive A, B, C, or D. end goto -scroll -line1403 call -header | begtype If a you wish to put more than one command on a line, the vertical bar "|" is useful. When used with an IF command and the test for the IF conditions fail, the entire rest of the line will be ignored. Multiple commands within a BAT statement is very useful when combined with the IF command. For example: BAT IF %A = abc TYPE this | CALL -that | GOTO -other If a comment is needed within a BAT program, the "*" (star) character is useful. When used after the word BAT, all characters which follow will be ignored. For example: BAT * This is a comment to the programmer. end goto -scroll -line1404 call -header | begtype That's about all the help there is!
