Most of the differences between the AMOS and A-Shell versions are only relevant to system-level programs, but there are some differences that may affect ordinary users. One is that the Ctrl+P command, under the A-Shell version of INFLD, brings up a screen snapshot utility. The utility gives you the option of printing a copy of the screen, and/or just saving it in the file <jobname>.buf. If saved, subsequent pictures will be appended to this file, creating a snapshot log which could be useful in a variety of situations (documentation, error reporting, etc).
The name of the screen snapshot capture file can be changed using the –b and –ba A-Shell command line switches.
