st: RE: can I use a global macro as a trigger?

["Radwin, David" <dradwin@rti.org>]

Melanie,

Yes, you just need quotation marks around the global macros, like this:



global type standard

if "${type}"=="standard" {
	display as result "Standard scenario."
	}

else if "${type}"=="special" {
	display as result "Special scenario."
	}


This is legal usage for the programmer's -if-, also known as the -if-
command. See -help ifcmd- for details.
