You pass the parameter without the dash(-) like:

\\server\location\prog.exe t

In your startup prg file, you have a PARAMETERS statement at the top that accepts the parameter(s) passed in. In this case "t" would be passed in.

>How do I pass a parameter at the desktop level? The target on the desktop icon should read something like "\\server\location\prog.exe -t" where t is a flag.
