401.0. "Where did I come from ?" by CHAMBR::GUINEAU () Wed Feb 04 1987 15:32


Is there a way for an executing program to tell if it was invoked
interactively by a user (at the $) or if it was invoked from
within a command procedure ?

401.1	$TRNLNM	BRSSWS::LIDSKY	Just send 3 box tops and $10,000...	`Thu Feb 05 1987 06:38`	8
	You could translate the logical name SYS$INPUT. If run interactively the name will translate to a terminal. If run from a command procedure it will translate to a disk.

	Not necessarily. If either of the following commands appear in the .COM file before the image is invoked, SYS$INPUT will equate to the terminal: $ DEASSIGN SYS$INPUT or $ ASSIGN[/USER] SYS$COMMAND SYS$INPUT tom_p

	.1 looks good. The use here wouldn't redirect SYS$INPUT. If fact the program relies upon the file for input. Thanks! John
