Returns information about the program execution stack. The $STACK intrinsic function has both a one-argument form and a two-argument form.
Syntax (One-Argument)
$STACK(<num>)
If num is 0, returns the command with which this FreeM instance was invoked.
If num is -1, returns the current program execution stack level.
If num represents a valid program execution stack depth above 0, returns one of the following values indicating the reason for which the referenced program execution stack level was created:
$$If $STACK(<num>)="$$", program execution stack level num was created as the result of an extrinsic function call
If $STACK(<num>) returns a valid M command, the referenced program execution stack level was created as a result of the m-command command.
Syntax (Two-Argument)
$STACK(<num>,"[ECODE|MCODE|PLACE]")
Returns the error codes, M program code, or entryref applicable to the action that created program execution stack level num.
