REXXUTIL Information and Samples

The following attempts to better explain some of the powerful features provided by OS/2 V2's dynamic link library; REXXUTIL.DLL (Rexx utility functions). REXXUTIL functions are described in the online 'REXX Information' reference and the 'OS/2 2.0 Technical Library Procedures Language/2 REXX Reference' publication (order number S10G-6268). The information following is intended to provide a more detailed description of some of the functions.

One should realize that many of the functions provided by REXXUTIL have origins with Presentation Manager WinXXX calls. The 'OS/2 Technical Library Presentation Manager Programming Reference Vol2' publication (order number S10G-6265) can be reviewed for more information.

Some of the functions used/explained:

like folders, programs, and shadow objects using Rexx. This section for the most part includes parameter information which was gathered together from various sources of information. know its objectid.
 * SysIni:Using REXXUTIL's SysIni function one can modify many settings of the WorkPlace Shell as well as change other applications settings that make use of *.INI files such as the system OS2.INI and OS2SYS.INI.
 * SysCreateObject: (PM WinCreateObject - Create Workplace Object) Using REXXUTIL's SysCreateObject function one can create various objects;
 * SysSetObjectData: (PM WinSetObjectData - Set Object Data) Using REXXUTIL's SysSetObjectData function one can change an objects characteristics (of an already created object, if you know its objectid).
 * SysDestroyObject: (PM WinDestroyObject - Destroy Workplace Object) Using REXXUTIL's SysDestroyObject one can delete an object created if you

Misc Notes:

If one views the *.RC files located in your bootdrive:\OS2 directory you can learn a lot about the various INI settings and folder structure. Review INI.RC and INISYS.RC files, they are used to create your OS2.INI and OS2SYS.INI files.

Some of REXXUTIL's functions are only available when using the very latest REXX20 PACKAGE which consists of the very latest REXX fixes and enhancements for OS/2 V2. So should you have problems running any of the sample programs you should make sure your system has the vary latest REXX20 updates.

Change Log: 04/30/92 - Added information about DuplicateFlag parm - Added more setup string information from manuals 06/02/92 - Added information about breaking Title line character "^" - Added information about adding multiple DOS_DEVICE statements - Added code to SHADOW.CMD to make shadow object of a file !!NOTE!! - The REXXOS2 fixes are required to make some of the newer samples work properly.

06/30/92 - Added information regarding two new REXXUTIL functions: SysSetObjectData and SysDestroyObject, also two new samples STARTDOS, BOOTDOS (Thanks to Rick McGuire) 07/13/92 - Reorganized the way the material is presented. Also added more sample Rexx routines REBUILD, OBJCLASS and LPTADD, descriptions follow. Also changed parm CONCURRENTVIEW to CCVIEW (Thanks Dan Kehn, Felix Sawicki) 07/15/92 - Updated entire document as I mistakenly truncated it at 80 characters. Rewrote some sample Rexx routines so they do not extend beyond 80 characters. Also updated the SysSetObjectData description to show how can open an object (Thanks Rick). Added information about creating multi-line titles, carat works for two line titles but not more than 2. New samples, OBJECTID and FONTS included, descriptions follow. 07/29/92 - Corrected an error I made when I broke the setup lines into multiple lines. I needed to add ||'s to make sure they concatenated without spaces (Thanks Rick). Also added information regarding changing some System Settings (added  new section after sample Rexx code). Also added warning in REBUILD.CMD sample about replacing Folder objects. Also added new sample ICONRES.CMD which builds a folder containing many of the OS/2 V2 installed icons using system DLL files.

This append consists of multiple pieces of information:


 * 1) Large block of text containing information that pertains to the subject. (TEXT INFORMATION)
 * 2) Sample Rexx code, some complete programs, others code fragments:
 * 3) * (FOLDER.CMD) Creates a folder and program objects in the folder

Help information regarding the SysCreateObject function of REXXUTIL
Function: SysCreateObject Syntax: result=SysCreateObject(classname, title, location <,setup>, <,duplicateflag>)

classname:The name of the object class.

title: The object title.

location: The object location. This can be specified as either a descriptive path (for example, OS/2 System Folder\System Configuration) or a file system path (for example, C:\bin\mytools).

setup: A WinCreateObject setup string.

duplicateflag: This parameter indicates what action should be taken when the Setup string specifies an object ID, and an object with that object ID already exists. If the setup string does not give an object ID, a duplicate object will be created.

result The return code from WinCreateObject. This returns 1 (TRUE) if the object was created and 0 (FALSE) if the object was not created.

Purpose: Create a new instance of an object class.

Help information regarding the SysSetObjectData function of REXXUTIL
Function: SysSetObjectData Syntax: result=SysSetObjectData(name, setup)

name: The object name. This can be specified as an object id (for example) or as a fully specified file name.

setup: A WinCreateObject setup string.

Purpose: Alter the settings of an existing object. Can also be used to open an instance of an object: /* open up the system folder */ call SysSetObjectData '', 'OPEN=DEFAULT;'

See the description of the SysCreateObject location and setup strings following for an explanation of the parameters.

Help information regarding the SysDestroyObject function of REXXUTIL
Function: SysDestroyObject Syntax: result=SysDestroyObject(name)

name: The object name. This can be specified as an object id (for example ) or as a fully specified file name.

Purpose: Destroys an existing object.

See the description of the SysCreateObject location parameter following for an explanation of the object name.

SysCreateObject Parms
The SysCreateObject parameters are now explained in more detail.

Remember syntax is... result=SysCreateObject(classname, title, location <,setup>, <,duplicateflag>)

classname: A registered object class defined to the system. Of particular interest are the WPFolder/WPProgram/WPShadow classes. Note using the sample Rexx code included in the SysQueryClassList function help screen one can list all of the registered classes: call SysQueryClassList "list." do i = 1 to list.0 say 'Class' i 'is' list.i end title: Easy one, the objects title you want to use. If you wish to break the title line use the carat "^" symbol in the title. Ex. 'First line^Second Line' This works to break a title into two lines. However to break a title into more than two lines you need to separate the title lines with a hex 0A (line-feed) character.

Rexx example: h0A='0A'X title='First'h0A'Second'h0A'Third'

location:

The objects location can be specified as either a descriptive path (for example, OS/2 System Folder\System Configuration) or a file system path (for example, C:\bin\mytools). However by looking at the INI.RC file one can see a use of other "locations", such as. If this is used as a location then your object will reside on the WorkPlace Shell desktop. If you are creating a folder or program object you should make sure you use the setup string option and give that folder a unique OBJECTID. We'll see how this works later.

HINTS: Here are some predefined object ids of system folders. Also if you are thinking of placing an object in the Startup Folder, make it a shadow of an object.
 * The Desktop.
 * The Startup folder.
 * The System folder.
 * The Templates folder.
 * The System Setup folder.
 * The Information folder.
 * The Drives folder.
 * The hidden folder.

setup:

This field needs the most explaining, a larger section following details many of the available setupstring parameters. The setupstring field contains a series of "keyname=value" pairs separated by semi-colons that change the behavior of an object. Each object class documents its keynames and the parameters it expects to see.

duplicateflag:

There are three possible values for this parameter: FailIfExists - No object should be created if an object with the given object already exists. This is the default and maps to the PM creation flag, CO_FAILIFEXISTS ReplaceIfExists - If an object with the given object ID already exists, the existing object should be replaced. Maps to the PM creation flag, CO_REPLACEIFEXISTS. UpdateIfExists - If an object with the given object ID already exists, the existing object should be updated with the new information. Maps to the creation flag, CO_UPDATEIFEXISTS. (Only the first character is required/examined, i.e. F, R, or U)

ALL parameters have safe defaults, so it is never necessary to pass unnecessary parameters to an object.

Setup Strings
What follows are both WPFolder and WPProgram setup string parameters. Their various key names, values and a short description follow each item. The <> item is there to give you an idea of what Workplace Shell settings "page" you would find this information on.

System Settings
During our attempts at customizing the shell using REXXUTILs for newly created workstations we discovered many items can be controlled. Our first attempt was to turn off the default setting for Workplace Shell Print Screen. We wanted it disabled instead of enabled (saves our customers from accidentally printing the workplace shell screen contents 🙂 From there we learned other items could be changed:

Remember the basic SysIni call is: result = SysIni([inifile], app, key, val)

Note: Some items if changed did not seem to take effect until the next reboot.

To see the menu items that can be changed go to: OS/2 System / System Setup / System, Window tab

Button appearance for windows /* Hide button = 1 plus hex 0 */ result = SysIni('USER', 'PM_ControlPanel', 'MinButtonType', '1'||'00'x) /* Minimize button = 2 plus hex 0 */ result = SysIni('USER', 'PM_ControlPanel', 'MinButtonType', '2'||'00'x) Animation /* Enabled = hex 01 00 00 00 */ result = SysIni('USER', 'PM_ControlPanel', 'Animation', '01000000'x) /* Disabled = hex 00 00 00 00 */ result = SysIni('USER', 'PM_ControlPanel', 'Animation', '00000000'x) Minimize button behavior /* Hide Window = 1 plus hex 0 */ result = SysIni('USER', 'PM_ControlPanel', 'HiddenMinWindows', '1'||'00'x) /* Minimize window to viewer = 2 plus hex 0 */ result = SysIni('USER', 'PM_ControlPanel', 'HiddenMinWindows', '2'||'00'x) /* Minimize window to desktop = 3 plus hex 0 */ result = SysIni('USER', 'PM_ControlPanel', 'HiddenMinWindows', '3'||'00'x) Object Open Behavior /* Display existing window; delete CCVIEW key */ result = SysIni('USER', 'PM_Workplace', 'CCVIEW', 'DELETE:') /* Create new window; CCVIEW key set to 'ON' */ result = SysIni('USER', 'PM_Workplace', 'CCVIEW', 'ON'||'00'x) To see the menu items that can be changed go to: OS/2 System / System Setup / System, Print Screen tab

Print Screen /* Disable print screen */ result = SysIni('USER', 'PM_ControlPanel', 'PrintScreen', '0'||'00'x) /* Enable print screen */ result = SysIni('USER', 'PM_ControlPanel', 'PrintScreen', '1'||'00'x)
