I'd look for the file REXXTUT2 on whatever BBS you know that carries
OS/2 stuff, but here's an example program you can modify:

/* REXX Code to demonstrate object creation and deletion */
 call rxfuncadd sysloadfuncs, rexxutil, sysloadfuncs
 call sysloadfuncs

 parms="EXENAME=*;Parameters=%;PROGTYPE=WINDOWABLEVIO;"
 parms=parms||"ICONPOS=70 90;"                   /* % of full screen */
 parms=parms||"ICONFILE=E:\ICONS\EXPLOSIV.ICO;"  /* choose your own icon */
 parms=parms||"OBJECTID="        /* ID for object */

 call SysCreateObject "WPProgram", "Indicator",
"",parms,"U"
 /*   ^                ^                ^          ^            ^     ^
      function     type of object      name      location     stuff  update */

 if result=0 then do; say 'unable to set data, result='result; return 1; end
 /*   ^ result holds the result of the previous 'call' */

 say 'waiting three seconds before deleting'
 call syssleep 3
 say 'now deleting indicator'

 if \SysDestroyObject("") then say 'Unable
to remove object'
 /* this is another way to use a function */
 /* what this really does is create an icon for an OS/2 program object
    and then deletes it */

 * KWQ/2 1.2g * Whips & chains?  That's a hardware problem!
