Description
REXXSEM is an OS/2-native DLL which allows REXX scripts access to native OS/2 semaphoring APIs. A few other goodies are thrown in which can greatly simplify your REXX code in a number of other areas. Over and above the simple API calls that OS/2 allows (all of which are available through RXSem), RXSem will keep track of your semaphores for you, allowing you to query RXSem for which semaphores you have in use for your given process.
RXSem is also developer-friendly with a unique capability for returning error messages that describe the current problem instead of aborting your script, as is normal for REXX libraries. Finally, a few other goodies are thrown in which can greatly simplify your REXX code in a number of other areas (priority settings, process detection and killing, launching Netscape via DDE, word wrap, set window title).
Note that this program was developed before REXXUTIL supported semaphores, that version of REXXUTIL comes with all variants of OS/2 Warp. While this DLL has some more fine grained control in some respects than what REXXUTIL offers you should look into the latter functions first since they are effectively built into the OS.
