Andre,
Executing the program
/**/
CALL RxFuncAdd 'SysSetObjectData','RexxUtil','SysSetObjectData'
CALL SysSetObjectData '\\server1\cdrive\CONFIG.SYS','OPEN=SETTINGS'
EXIT
opens a WPS object for \\server1\cdrive\config.sys - as shown in the first attachment.
Just for kicks, I created a WPS object for the Win-OS2 Notepad.exe application, and entered
\\req1\cdrive\config.sys in the parameters. req1 is the machine I was working on, i.e. the current machine.
The Win-OS2 Notepad opened the file \\req1\cdrive\config.sys - without converting the file name to a drive letter, even though \\req1\cdrive = c:\
