- Editor version V1.1 Informtion for use.
-
- A brief description of the files required:
-
-
- Volume in drive B is MSB-PASWRK
- Directory of B:\
-
- NAME-OF DSK 13 5-16-84 12:10a
- MSBEDIT EXE 54784 5-19-84 1:02a
- EDIT-MOD PAS 21192 5-19-84 12:46a
- DIR LST 0 5-19-84 10:14p
- EDT-MAIN PAS 24596 5-19-84
- 7 File(s) 60416 bytes free
-
- MSBEDIT.EXE is the editor, you may rename this to any file
- name you desire to call it. EDIT-MOD.PAS is the source code of
- the module it contains approx 600 lines of source code.
- EDT-MAIN.PAS is the source code of the main module, also about
- 600 lines long. This if for some reason you modify it, you
- must recompile and link these modules together with the linker.
- You must also include CLS.OBJ in the link command or delete the
- line " Procedure cls; external; " from the source program so
- the linker does not expect to find it. I included mine, as
- well as the .ASM source so you can decide.

-
- *** SUMMARY OF EDITOR COMMANDS ***
- --------------------------
-
- All editor commands are recognized by their first letter.
- Users have the choice of using the first letter, or by typing
- the entire command. Commands will NOT be recognized by a
- partial command if more than the first letter is used.
-
- Ex: f for find. Commands currently must be typed in
- lower case, if you desire, change the table to uppercase and
- recompile.
-
- *** COMMANDS WHICH ACT ON THE CURRENT LINE ***
- --------------------------------------
- B[OTTOM] | Reset the current line pointer to point at the last li
- line in the file. The last line is printed. The
- message "EMPTY INPUT FILE" is printed if the file is
- empty. |
-
- EX: > b
- > bottom
-
- F[IND][-]/string[/] | Find the first occurrence of the string in the
- edit file, starting the search at the line
- following the current line. If the string is
- found, the line containing string is printed.
- Otherwise, STRING NOT FOUND is printed, and
- the pointer is not reset. If the string is
- preceded with a -, the search is performed
- backward through the file.
-
- Ex: > f/this string/
- > f-;strings may be any length;
- > find/.
-
- N[EXT][<NUMBER>] | The simplest form (just n), the line following the
- current one is printed. If there is a positive
- number or negative integer in the command stream
- the current line is moved forward or backward that
- many, or as many to the end or top of file. If there
- is no next line then a message "END OF INPUT FILE" or
- "TOP OF INPUT FILE" is printed and the pointer is not
- moved. |
-
- EX: > n
- > n3
- > n-2
-
- [T]OP | Make the first line the current one and print it.
- "EMPTY INPUT FILE " is printed if there are no lines
- in the buffer. |
-
- EX: > t
- > top
-
- *** EDITOR DIRECTIVES ***
- -----------------
-
- A[PPEND]/STRING/[<COLUMN NUMBER>]
-
- | Append the string to the end of the current line
- (if no column number is specified) and print the
- new line. If column number is specified, append
- the string to the line starting in that column.
- Any characters after the inserted string are lost. |
-
- (assume current line = "MARY HAD A LITTLE")
- EX: > a/la/
- MARY HAD A LITTLE la
- > a/mb/
- MARY HAD A LITTLE lamb
- > a/./5
- MARY.
-
- C[HANGE]/OLD STRING/NEW STRING/
-
- | Change the first occurrance of old string to
- new string. If old string is not present in the
- line an appropriate message is printed. If the
- new string is not specified the old string is
- replaced with the null string. Assume that a null
- string precedes all lines. |
-
- EX:
- Jack be mimble, jack be quick
- > c/mi/ni/
- Jack be nimble, jack be quick
- > c/jack/Jack/
- Jack be nimble, Jack be quick
- > c//Black/
- BlackJack be nimble ....
-
- D[ELETE][<STRING>|<NUMBER>]
- | Delete the current line (if optional string or
- number is not specified) and reset the current line
- pointer to the line following the one deleted.
- If the last line is deleted, the message "BOTTOM OF
- "FILE" is printed. If d{number} is used, that many
- lines is deleted from the current line. By using
- d<string> will delete line, and all following lines
- until string is found. |
-
- EX: > d { delete only the current line }
- > d2 { delete current line and one following }
- > d-2 { delete current line and one previous }
- > d/it/ {delete current line and all following
- until "it" is found }
- > ^d! { delete all lines in buffer }
- > d! { delete current and all following lines }
-
- I[NSERT] | Enter the insert mode. Lines are inserted after the
- current line. The input prompt is the * To exit the
- insert mode type a backslash with nothing else on the
- line (\). |
-
- EX: > i { message displayed: MODE> INSERT }
- * <type new text here><cr>
- * \
- MODE> COMMAND
- > { back to command level }
- the last inserted line is the current line, and
- is printed.
-
- P[RINT][<STRING> | <NUMBER>]
- | Print the current line. If a number is specified
- the current line plus that number is displayed.
- The current line pointer not moved.
- p<string> prints the first line containing string
- if found. |
-
- EX: > p
- > p2
- > p/THIS
- > p-/THAT
- > ^p! { print whole buffer }
-
- R[EPLACE] | The current line is deleted and the editor enters
- insert mode. (See insert command for more
- information on insert). The last line entered is
- the new current line. It is printed. |
-
- EX: > r
- * new line
- * newer line
- * \
- MODE> COMMAND
- newer line
- >
-
- *** SYSTEM DIRECTIVES ***
- -----------------
-
- A[BORT] | Cancel the current edit file. Do NOT update the
- external edit file. This command must be spelled
- out because of the append command. |
-
- EX:
-
- > abort
-
- S[TOP] | Stop the current session. Write the internal buffer
- out the external disk file, named on entry. |
-
- EX:
- > s
- > stop
-
- *** ENVIRONMENT DIRECTIVES ***
- ----------------------
-
- H[EADER]<COLUMNS> | This procedure displays a column of numbers
- 1 .. <columns>; if columns is > 72 then only
- 72 are displayed. This is useful for finding
- which column characters should be aligned in.
- this line is never inserted into the file.
-
- V[ERIFY] | The verify flag is toggled on or off. The verify flag
- is used by directives such as change or next to display
- their results. The verify flag is initialized to on
- when the editor is first loaded. |
-
- EX: > v
- > verify
-
- Any edit directive can be preceded by plus or minus some
- integer. This will add (or subtract) that number to (or from)
- the current line pointer before applying the edit directive.
- For example:
- > +2p : prints the second line past the current line.
- > -1i : insertion mode is entered; insertion before the current
- line.
-
- The editor places special significance on the following
- symbols: ^ = reference to the TOF mark. ! = process as
- infinity (maxint). For delete, print and anywhere that a
- number may appear.
-
- The editor does not display any line numbers because line
- numbers are not an intrinsic part of the file. However, you
- may still use line numbers to reference any line. For example:
- > 10c/it/is will change it to is on line 10. Delimiters at the
- end of a command are optional.
-
- Example: f/this stiring/ is equivelent to f/this string
- if both delimiters are used they must be identical, and should
- not appear in the string.
-
- To start the editor: at the DOS prompt type: MSBEDIT
- <FILENAME>, if you enter MSBEDIT without the file name you will
- be prompted by system: "EDFILE:", type the filename to be used
- here. This is because DOS needs a default name in case the
- program passes a bad one. You will be prompted by the PASCAL
- program to enter the filename again. If you use the filename
- as a command parm then the system prompt will not appear.
-
-
- If you plan to do any work to the source code I suggest
- that you read and understand what the code is doing before you
- modify it. I was unable to leave the comments in it I
- orignially planned on because I was running out of free space
- on disk and compilations, and .LST files were getting out of
- hand with it. Sorry it is so bulky.
-
- I would not recommend it on very large files, say more
- that 600 lines unless you have more that 128 bytes of memory.
- I have 128Kb and under DOS 2.00 found operation fairly slow
- with large files. Especially on find or change commands.
- However it works quite nicely on small to medium files. I
- believe it is somewhat better that EDLIN at least.
