Capture SYSPRINT

smaru · New User Joined: 22 Oct 2008 Posts: 49 Location: India

I have a Rexx exec that calls a program (actually I think it might be an assembler program, it's vendor supplied). When it runs, there are displays from the program that show up on the screen that I would like to capture to a dataset.

I've tried allocating SYSPRINT, SYSOUT, TERMINAL, etc. and assigning an output dataset name to these DD's, but nothing gets captured.

Is there another way that I can capture these displays ?

Thanks for any help.

Try OUTTRAP, but take heed of the restrictions:

This is the way i tried Outrap

Open X = Outrap (......)
Address TSO ( <Rexx Command>)
Close Outrap.

But it did not capture the display statements in the outrap. Just wanted to make sure, Is this the same thing you meant.

I have tried this option earlier itself.

Thanks for the reply. Any other suggesstions

What are the "open" & "close"? Are those new REXX instructions?

Try using OUTTRAP the following way:

Hi Pedro,

Thers is a TSO command exeuting (may b Assembler) and when I execute the command it displays some messages (not on panel). I suppose those are getting displayed in Sysprint, I wanted to capture these messages in to a dataset.

Hi Marso,

That is what I have tried and it did not work.
The messages my command executes are displayed not the outrap count.

Check with the vendor. If they're using TPUT or WTO, as I pointed out earlier, then you can't capture the output. If they are indeed writing to a datatset, then you just need to read the contents of that dataset.

Probably, that might be the case.

Just wanted to confirm One more thing,

When you execute rexx command with a simple statement SAY "Hello".

I assume the message "Hello" is displayed in ISPF panel (Is that correct??)

No, it is displayed on your default output device (usually SYSTSPRT/terminal).

Exactly.
So the message from SYSTSPRT cannot be captured ? ?

The point is that putting text on the screen can be done using several methods. Some of those ways cannot be captured. Programs should use a method that allows capture, but some do not. It might simply be a case of the developer not knowing. You should be able to submit a requirement to the vendor.
