I am trying to get a legacy Object Rexx script (developed with v 2.1) to run on a Windows Server 2003 R2 platform, and I'm getting various problems with things like spawning of windows commands and rexx scripts, RXQUEUE's to synchronise them, and a strange error warning of 'regina.exe - Application Error The instruction at "0x77bd92f9" referenced memory at "0x00000000". The memory could not be "read".' if I try to run the script from a command prompt (i.e. outside the Object Rexx Workbench). (Very odd since as far as I can tell regina.exe is not even installed on the machine). Can you recommend a version of Object Rexx that is compatible with Windows Server 2003 R2 that might be able to run this 2.1 script? Is 2.1 Object Rexx supposed to be compatible with Windows 2003?
