I think I found a bug in the behaviour of an OSA ICC: Experienced CMS programmers know that to start tracing a looping XEDIT macro can be done by entering a TS command in the command area. But, first one needs to get the commandline. A bit difficult as the 3270 is in "input inhibited" (a green led on real 3277's, an X with the clock icon in the status area nowadays) and the display is in fullscreen mode.
To get the command line, what is required depends on the terminal type - a real non-SNA 3270: press the reset key (the stop input Inhibited) and press enter, or PA1, .. - in SNA: press the ATTN key then enter, or PA1, ... - TN3270 with PCOMM: press ATTN Today, on my PCOMM connected to an OSA ICC on a z10, I found no means to break in (apart from "Communication" -> "Disconnect" or using some other userid to send a CP Message/Warning to the user in trouble). An OSA ICC is supposed to simulate a non-SNA 3270, it does it well, except for this problem. Any comments? Is it working on your system? -- Kris Buelens, IBM Belgium, VM customer support
