Jeff - we setup a batch file to run PVX programs, then invoke that via the scheduler. Here is an example.
Program here is IMW_SS
Rem Set path to Mas90/HOME folder
CD c:\Sage\2014\MAS90\HOME
REM Launch program
REM Parameters here are ABC = company, UUU = usercode, 0777 = User Password
START /B PVXWIN32.EXE ../launcher/sota.ini ../soa/startup.m4p -ARG DIRECT UIOFF UUU 0777 ABC IMW_SS
EXIT
