ΓòÉΓòÉΓòÉ 1. Introduction ΓòÉΓòÉΓòÉ About... Installation REXX Registration REXX Deregistration REXX Registration Tips ΓòÉΓòÉΓòÉ 1.1. About... ΓòÉΓòÉΓòÉ This is version 1.9 of RxExtras, released in February, 1994. RxExtras is a set of functions to enhance OS/2's REXX programming language, and is accompanied by additional functions to be used by other PM Rexx-based software (VisPro/Rexx and VX-Rexx, among others). Some of the functions provided by RxExtras can be accomplished by various other means using "pure" OS/2 REXX code, but RxExtras provides an easier interface and more efficient processing. Take the RxSort() function as an example. You can certainly write REXX code to write a stem to a file, run the external SORT program, and read the sorted data back into a stem. The RxSort() function of RxExtras saves a lot of disk I/O; 1. writing the stem to disk. 2. the SORT program reading the file from disk. 3. the SORT program writing the file back to disk. 4. reading the sorted file back into a stem. Plus, with RxSort(), you only need 1 line of code to accomplish the entire task! Once RxExtras is registered to your REXX interpreter, you can take advantage of any RxExtras functions in your existing and future REXX-based programs. ΓòÉΓòÉΓòÉ 1.2. Installation ΓòÉΓòÉΓòÉ To install RxExtras, place the RxExtras.DLL file in any subdirectory which is part of your LIBPATH statement (LIBPATH is found in your CONFIG.SYS file). For example, you could place RxExtras.DLL in your x:\OS2\DLL subdirectory (by default, x:\OS2\DLL is part of your LIBPATH when you install OS/2). However, it is recommended that you place RxExtras.DLL in some other subdirectory. The reason for this is that should you have to reinstall OS/2, RxExtras.DLL will not automatically be reinstalled with OS/2. All REXX-based programs that require RxExtras.DLL will fail until such time as you manually copy RxExtras.DLL to your x:\OS2\DLL subdirectory. A better, more flexible approach is to make a subdirectory (preferably on a drive other than where OS/2 is installed) for all your add-on *.DLL files, which includes RxExtras.DLL. For example, make a subdirectory called y:\USER\DLL and place RxExtras.DLL in there. Then, edit your CONFIG.SYS file, and add ";y:\USER\DLL" to the end of your LIBPATH. Save CONFIG.SYS and reboot (you must reboot in order for this last change to take effect). Once you've done this, you will never have to modify CONFIG.SYS again, no matter what *.DLL file you add to your system. Just place your new *.DLL file in y:\USER\DLL, and the system will automatically find it when needed. After installing RxExtras, you must register the APIs in order to use them. ΓòÉΓòÉΓòÉ 1.3. Registering RxExtras ΓòÉΓòÉΓòÉ In order to use any REXX features of OS/2, you must have installed the REXX Interpreter. When you installed OS/2, you may have chosen to not install REXX. If this is the case, open your Selective Install icon and install REXX before continuing. In order to take advantage of RxExtras' REXX APIs found in RxExtras.DLL, you must first "register" the APIs with OS/2's REXX Interpreter. This is true of any and all REXX-based *.DLL files. The process is rather simple. In your *.CMD file (or within your PM REXX-Based program), simply code these 2 lines: Call RxFuncAdd 'RxExtra', 'RxExtras', 'RxExtra' Call RxExtra 'Load' Note: You must code these 2 lines so that they execute before any RxExtras APIs are referenced elsewhere in your program. Once you have done this, your REXX program can take full advantage of RxExtras' APIs (functions). Additionally, all future sessions of REXX-based programs will likewise have access to the RxExtras APIs. In other words, once these APIs are registered, they have a global effect across your entire system; all OS/2 REXX sessions will be able to use them. They stay registered until you reboot or intentionally deregister them. Double-click here for some tips and advice on REXX API registration techniques. ΓòÉΓòÉΓòÉ 1.4. Deregistering RxExtras ΓòÉΓòÉΓòÉ When you are through with the RxExtras APIs, it is possible to deregister them from your system. The advantage to doing this is that the shared memory they occupied will be released for other programs to use. The disadvantage is that if you wish to use the APIs once more, they must be registered once more. This requires some disk I/O activity to locate the RxExtras.DLL file and load its contents into memory. Warning: If you chose to deregister the RxExtras APIs the affect is global across your entire system. No other REXX-based programs will have access to the APIs and they will in all likelihood fail miserably! To deregister the RxExtras APIs, simply code this line anywhere in any *.CMD file or any other REXX-based program: Call RxExtra 'Drop' Upon execution of the above line, the APIs will be flushed from memory when the system finds it convenient so to do. Double-click here for some tips and advice on REXX API registration techniques. ΓòÉΓòÉΓòÉ 1.5. Registration Tips ΓòÉΓòÉΓòÉ A good technique for registering any and all REXX API packages (including RxExtras) is as follows: o Define a STARTUP.CMD file in the root directory of your OS/2 boot drive. o Register, within STARTUP.CMD, any and all REXX API packages that you frequently use. o In each *.CMD file or REXX-based program that requires the API: 1. Test for the pre-registration of the API package and save the results in a REXX variable. 2. If the test indicates that the API is not yet registered with REXX, then register it according to the API package's instructions. 3. Just before exiting your program, if the status variable shows that the API was not pre-registered, then deregister it. This method ensures that: 1. Your *.CMD or REXX-based program has access to the APIs it requires. 2. Your REXX environment, in terms of the pre-registered APIs, is restored to its native state before your program exits. This makes for a very well behaved, tolerant program. Specifically, for RxExtras: In your x:\STARTUP.CMD file, place: Call RxFuncAdd 'RxExtra', 'RxExtras', 'RxExtra' Call RxExtra 'Load' In all of your *.CMD and other REXX-based programs that require the RxExtras APIs, place: RxExtraAPI = RxFuncQuery('RxExtra') If RxExtraAPI \= 0 Then Do Call RxFuncAdd 'RxExtra', 'RxExtras', 'RxExtra' Call RxExtra 'Load' End before any other references to RxExtras APIs, and then just before your program exits, use: If RxExtraAPI \= 0 Then Call RxExtra 'Drop' Notice that registering your RxExtras APIs in the STARTUP.CMD file makes the need for the per-program test of pre-registration superfluous. However, it is a good programming practice to code these lines anyway. One reason is that if you give a copy of your program to someone else to use, they might not have registered the APIs in their STARTUP.CMD file. Another reason is that since registration in STARTUP.CMD puts these APIs in memory and leaves them there, you may decide (in the interest of saving memory) to remove the pre-registration from STARTUP.CMD. If you do, and you did not code the above tests (or you got a program from someone else and they did not code the above tests), your programs will no longer execute. CAUTION: Never blindly assume you can deregister any API functions when your program exits. A program that always deregisters the APIs when it quits only causes problems for everyone that uses it. If you are going to include code that deregisters an API (RxExtras or otherwise), you should do so only if you're certain it was not pre-registered when the program started! ΓòÉΓòÉΓòÉ 2.

VPRxx - VisPro/REXX toolbar support. ΓòÉΓòÉΓòÉ A new object for the VisPro/REXX toolbar (VPRxx) was uploaded to the HockWare section of CompuServe. When installed, it places a new object on the VisPro/REXX toolbar that represents RxExtras. If you place this object on your form, you can use it in the event tree view to get prototypes of all the RxExtras functions by dragging the object to the code window. This means RxExtras is now easier to use! And the online help for all the functions are available using the Help button of the Create Link dialog of the RxExtras object. If you have any suggestions, or are interested in other VisPro/REXX objects, contact the author of RxExtras. ΓòÉΓòÉΓòÉ 4. VX-REXX Insert Code... Support ΓòÉΓòÉΓòÉ When coding using Watcom's section editor, you can use a popup menu to insert commonly used code into your application. You can add the RxExtras APIs to the Insert Code dialog if you wish to do so, by simply copying the RxExtras.MTC file that comes with RxExtras to the \VXREXX\SYSTEM directory. Once the copy has been done, you can use the Insert Code menu item to get prompted (and help assisted) support for coding RxExtras APIs in VX-REXX. If youn have any suggestions for this feature, please contact the author of RxExtras. ΓòÉΓòÉΓòÉ 5. RxExtras APIs ΓòÉΓòÉΓòÉ The listings for RxExtras APIs (functions) will designate which types of REXX programs can take advantage of them. Each API will have a box at the top of its description detailing in which environments it may be used: ΓöîΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓö¼ΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓö¼ΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÉ ΓöéOS/2 REXXΓöéVisPro/REXXΓöéVX-REXXΓöé ΓööΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓö┤ΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓö┤ΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÿ If you see "OS/2 REXX" in the above box for a function, you may use that RxExtras function in any *.CMD and/or other REXX-based program. If you do not see "OS/2 REXX", then you cannot use the API in a *.CMD file. If you see "VisPro/REXX" in the above box for a function, you may use that RxExtras function in any VisPro/REXX program. If you see "VX-REXX" in the above box for a function, you may use that RxExtras function in any VX-REXX program. APIs for VisPro/REXX and/or VX-REXX could possibly be used in other PM Rexx-based programs. Some experimentation may be necessary. ΓòÉΓòÉΓòÉ 5.1. Disc/File ΓòÉΓòÉΓòÉ These APIs deal with accessing information to, from, or about discs and files. Some of them are unique in that there are no standard REXX commands that will retrieve the information for you; RxExtras must be used in these instances. ΓòÉΓòÉΓòÉ 5.1.1. RxBootDrive ΓòÉΓòÉΓòÉ ΓöîΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓö¼ΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓö¼ΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÉ ΓöéOS/2 REXXΓöéVisPro/REXXΓöéVX-REXXΓöé ΓööΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓö┤ΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓö┤ΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÿ ΓöÇΓöÇΓöÇRXBOOTDRIVE()ΓöÇΓöÇΓöÇ Returns the drive from which OS2 was booted in the format 'X'. If you want a trailing ':' you must append one to the returned drive letter. Example: SAY 'My Boot Drive is' RxBootDrive() || ':' Output: My Boot Drive is C: /* perhaps */ ΓòÉΓòÉΓòÉ 5.1.2.

The lines in filename are assumed to be delimited by CR/LF characters. If filename does not exist, RXLINECOUNT raises an 'Incorrect call to routine' condition. Example: SAY 'There are' RxLineCount('C:\CONFIG.SYS') 'lines in Config.Sys.' Output: There are 117 lines in Config.Sys. /* perhaps */ ΓòÉΓòÉΓòÉ 5.1.3. RxListBoxFromFile ΓòÉΓòÉΓòÉ ΓòÉΓòÉΓòÉ 5.1.4. RxListBoxToFile ΓòÉΓòÉΓòÉ ΓòÉΓòÉΓòÉ 5.1.5.

Returns 'NOTREADY' for the following conditions: o A CD-ROM drive with an Audio CD loaded. o An empty floppy drive. o An invalid drive letter. Example: SAY 'Drive C: is a' RxQueryDriveType('C:') 'drive.' Output: Drive C: is a HPFS drive. /* perhaps */ ΓòÉΓòÉΓòÉ 5.1.6. RxRead ΓòÉΓòÉΓòÉ ΓòÉΓòÉΓòÉ 5.1.7.

The path(s) defined for searchpath will be used for the search. searchpath may be composed of several pathnames, each separated by a semicolon. Each pathname is allowed to have either a drive designator, a directory designator, or both. Currently, filename must specify a complete filename; no wildcard characters are accepted. If you supply the optional subdir\ qualifier, the effect is as if you had modified all the values of searchparh to include the addtional subdir\ value. For example, if searchpath contains 'F:\OS2;G:\USER', and you specify 'DLL\' for subdir,, the effect is the same as having specified 'F:\OS2\DLL;G:\USER\DLL' for searchpath and no value for subdir\. RXSEARCHPATH returns a fully qualified filename if it finds one, otherwise it returns NULL. Example: /* Find COUNTRY.SYS */ SchPath = 'C:\OS2\SYSTEM;D:\OS2\SYSTEM;E:\OS2\SYSTEM' SAY RxSearchPath(SchPath,'COUNTRY.SYS') Output: D:\OS2\SYSTEM\COUNTRY.SYS /* if found in D:\OS2\SYSTEM */ ΓòÉΓòÉΓòÉ 5.1.8.

If no label exists, it returns 'NO LABEL'. Returns 'Error Querying drive label' for an invalid drive letter. You may append an optional colon to the letter, but only the drive letter itself is required. Example: SAY 'Volume Label of drive C is' RxVolumeLabel('C') Output: Volume Label of drive C is MY DRIVE C /* perhaps */ ΓòÉΓòÉΓòÉ 5.1.9. RxWrite ΓòÉΓòÉΓòÉ ΓòÉΓòÉΓòÉ 5.1.10.

RXSWITCHTO will attempt to locate a session, by name, that matches in any part of its name to the contiguous characters defined by session For example, if session contains 'stem C', RXSWITCHTO will switch to the System Clock session, if it is active. If you desire to specifiy a complete name, use RXQUERYSWITCHLIST to obtain the full names of all executing sessions. RXSWITCHTO returns 'Switch Entry not found' if it cannot find a session name to match session.

Typically, it is used in conjunction with functions which do not permit the use of global file-name characters, to perform repetitive operations on files. An example of an editing operation is:- source = "foo.bar" wildCard = "*.baz" Call RxMatchWildCard source, wildCard /* result = "FOO.BAZ" */ In the editing process, the string is changed to uppercase. Global file-name characters (?, *, .) have two uses:- searching and editing. If they are specified in source, they are interpreted as search characters; in wildCard, they are interpreted as editing characters. This difference can be illustrated with an example using the COPY utility. The user types the following:- copy *.old *.new In the source, "*" acts as a search character and determines which files to return to the user. In the target, "*" functions as an editing character by constructing new names for the matched files. When used as search characters in source, global file-name characters simply match files and behave like any other search characters. They have the following meanings:- . The period (.) has no special meaning itself, but "?" gives it one. * The asterisk will form a match with any character, including a blank, or with the absence of a character. The matching operation does not cross the null character or the backslash (\), which means that only the file name is matched, not an entire path. ? The question mark matches 1 character, unless what it would match is a "." or the terminating null characters, in which case it matches 0 characters. It also does not cross "\". Any character other than * and ? matches itself, including ".". Searching is not case-sensitive. If a file name does not have a period (.), an implicit one is automatically appended to the end during searching operations. For example, searching for "foo." would return "foo". When used in wildCard, global file-name characters have the following meanings:- . The period (.) in the target synchronizes pointers. It causes the source pointer to match a corresponding pointer to the period in the target. Counting starts from the left of the pointers. ? The question mark copies one character, unless what it would copy is a period (.), in which case it copies no characters. It also copies no characters when the end of the source string is reached. * The asterisk copies characters from the source to the target until it finds a source character that matches the character following it in the target. Editing is case-insensitive and case-preserving. If conflicts arise between the case of the source and that of the editing string, the case of the editing string is used, for example:- source string: "file.txt" editing string: "*E.TMP" result string: "filE.TMP" copy file.txt *E.tmp -> filE.tmp RXMATCHWILDCARD returns :- ΓöîΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓö¼ΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÉ ΓöéReturn value ΓöéReason Γöé Γö£ΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓö╝ΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöñ Γöétext ΓöéThe result of editing the source and Γöé Γöé Γöéwildcard Γöé Γö£ΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓö╝ΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöÇΓöñ Γöé"Invalid parameter" ΓöéAn internal error occurred - contact theΓöé Γöé ΓöéRxExtras author.

Only the first character of 'Forever' is significant. 'Forever' is the default. ΓòÉΓòÉΓòÉ 6. RxExtras.LIB ΓòÉΓòÉΓòÉ RxExtras.LIB is a library file for use in C programming. If you want to use some of the functions in RxExtras in your own C code, you need to link with RxExtras.LIB when you are building your application. All functions exported from RxExtras.LIB are callable from REXX and therefore have the following function prototype :- ULONG Name(PSZ pszFnName, ULONG ulArgc, RXSTRING rxArgv[], PSZ pszQName, PRXSTRING prxReturn) The following is a list of all functions exported in RxExtras.LIB o RxRead o RxWrite o RxBootDrive o RxVolumeLabel o RxVarDump o RxStemCopy o RxExtra o RxSort o RxSwitchTo o RxQuerySwitchlist o RxListBoxFromFile o RxListBoxFromStem o RxQueryDriveType o RxSearchPath o RxGetItemFromListBox o RxSetSpinButtonRangeWithIncrement o RxSetSpinButtonCharRange o RxSetSpinButtonRangeFromStem o RxGetItemFromListBoxAtIndex o RxSetGlobal o RxGetGlobal o RxGetListBoxCount o RxListBoxToFile o RxListBoxToStem o RxAddItemAtIndex o RxMorphButtonToIcon o RxSearchItem o RxSetAccelTable o RxQueryAccelTable o RxQueryWindow o RxQueryClassName o RxQueryFonts o RxLineCount o RxMaximize o RxMinimize o RxRestore o RxThread o RxKillThread o RxSuspendThread o RxResumeThread o RxSetThreadClass o RxChangeThreadPriority o RxSetIcon o RxDrawBitmap ΓòÉΓòÉΓòÉ 7. RxExtras.CMD ΓòÉΓòÉΓòÉ RxExtras.CMD is a command file that will test all parts of RxExtras that can be run from the command line. A copy of this file is included here in case you delete it. You can easily copy the file from the Services->Copy menu item on the action bar and then paste it back into your favourite editor. ΓòÉΓòÉΓòÉ 7.1.
