I have some experience in this.  Is the mainframe running OS/400?  If that's the case, you'll need to install the IBM ClientAccess software, it comes with some utilities that will allow you to run OS/400 programs (RPG or COBOL) from the command-line.

Our mainframe is running z/OS, which is the successor to OS/390.  Should IBM ClientAccess work with this?

I doubt it.  I'm pretty sure it's for iSeries OS/400 only.  There may be something similar, though, for z/OS.

ClientAccess comes with a plethora of command-line utilities for accessing your iSeries programmatically, such as RMTCMD which allows you to perform a Call() to any compiled program.

Unfortunately, this is pretty much the end of my knowledge of IBM mainframes, sorry I couldn't be of further help.  I'm a Windows guy, I pretty much stay away from anything else unless I have to!
