OK, this may or may not help. What you are using may behave differently from what we use. We use NDM (ndmcli). First thing is that we are capturing all the screen output to a temp file. This output includes the Process Number. What we then do is within a script run the ndmcli session and pass all the information to it using << for a "here" document in a system command. then, once that piece of the routine is finsihed, we parse the temp log file for the Process Number, store it in a variable which is then passed to a second invocation of the ndmcli so we can pull parse for Completion Code data so we know if the process worked or not. Please understand what we are doing is different from what you might be doing in that A) we run NDM on a Unix platform and B) we are doing a file transfer from Unix to a Mainframe (so there are different parameters/options for NDM). What follows is a function that I put into a custom Perl Module for my team to use so they don't have to recreate all this code every time. Also, a lot of this is based on some old code that I found that someone else wrote which I then converted from Korn Shell to use in Perl and some of it I don't quite understand but I can make educated guesses at what it is for. YMMV with the following code sample. I would suggest looking at it, if it helps, great, if not, sorry. You may also want to compare it against code samples in the C:D manuals (if you can lay your hands on them - I used to have a stack of old ones but they got purged in general office cleaning years ago). This code is mean to be run as a subroutine function from within a Perl script.
