Terminating Scripts
In general, scripts terminate when flow of control reaches the "end" of the script. Since in long complex
scripts it may be difficult to provide flow-control to the "end" of the script, the script can be terminated at
any time using the VBScipt "err.raise" function:
call err.raise(errNo (int) , errorSource (string) , errorDescription (string))
The SR1 Basic Interface includes a built-in flag, SR1.Scripting.Terminate, which is set true when the
user presses the stop ( ) button on the scripting panel. A subroutine can be included in user
programs which checks the flag and ends the program:
sub checkterm()
if SR1.Scripting.Terminate then
call err.raise(-1,"checkterm","Manual Program Termination")
end if
end sub
By sprinkling calls to "checkterm()" throughout a script, the programmer can ensure that the script will
always terminate when the stop button on the scripting panel is pressed.
