Yes, they can all be captured. The only issue may be that if the command doesn't properly issue the responses then you may not be able to tell that the response is for the command you issued. But once you (a program) sets up a console, you can capture anything that appears on that console. For properly-written command processors the program can supply a response token on the command when it issues the MGCRE macro, and the command processor will include that token on the command response to the command. If the command processor does not support use of the response token, then the program has to capture everything coming to the console and find the responses among all the other messages the console may be seeing. -- Walt ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
