!(OPCSDEFS) Optical Printer Control System !(OPCSDEFS) NAME ! - execute a shell command from within OPCSDEFS file SYNOPSIS ! [command] EXAMPLES ! copy *.* \safe # run the DOS 'copy' command ! myprog 12 34 56 # run 'myprog 12 34 56' from DOS DESCRIPTION Like the !(OPCS) command, !(OPCSDEFS) executes commands from DOS in a DOS shell. But this allows the user to have programs executed automatically while the OPCSDEFS.OPC file is being parsed when the OPCS software is started. This is useful to initialize other pieces of hardware not associated with the OPCS software, or other modular programs that should be run as part of the initialization process. COMMAND STACKING As with all OPCSDEFS commands, it is recommended that you avoid 'stacking' more than one command on any one line (like you can with OPCS commands at the operator's prompt). Put each separate OPCSDEFS command on its own separate line to avoid parsing problems. BUGS You can't 'quote' commands with ! in DEFS files the way you can with ! at the OPCS prompt. That is to say that the following WON'T WORK in an OPCSDEFS file: ! myprog 12 34 56 ! ramp a 1 12 ORIGIN Adapted after examples set by such UNIX utilities as VI, ED, etc. UNIX is a trademark of AT&T.
