Hi everyone,

I discovered labtalk macros a while ago, and wanted to use one macro including arguments. As always I wanted to make sure there is an error when no arguments are provided, so the users knows how to use the macro.

The only way I found is rather ugly:

def ArgumentTest {
	string Argument1="%" + "1";
	string Argument2="%" + "2";
	if ("%1" != Argument1$ && "%2" != Argument2$) {
		type "Two Arguments %1 and %2";
	}
	else {
	        type "Some error message";
	}
}


If no argument is provided, %1 is used as literal text %1.

Invoking with no or just one argument triggers the error message:
ArgumentTest Test


Is there a smoother way? How to prevent %1 from being substituted before running the commands?

Hi Greg,

thanks for the answer, thats a lot smoother.

However, I wonder why I never found that page before. Searching for "labtalk check arguments", "labtalk test for arguments", "labtalk empty arguments" and lots more just came up with the examples on e.g. http://qhwiki.originlab.com/~originla/howto/index.php?title=Tutorial:Advanced_Scripting_using_LabTalk#Defining_a_LabTalk_Script_Macro_Command.

Funny.

Nevertheless, thanks for the help.

Regards,

Johannes

I found this in the LabTalk Help:

Def TypeArgs
{
if (macro.narg != 3)
{
type "Error! You must pass 3 arguments!";
}
else
{
type "The first argument passed was %1.";
type "The second argument passed was %2.";
type "The third argument passed was %3.";
}
}
