TestStand function to change Upper/Lower Case?

[Mike Seibel]

How can I perform a "toUpper()" on a variable using TestStand expressions? I want to force all upper case on a string that a user has input, before validating it.

I know I can do this in a VI, but I would hope that TestStand could do this. There appears to be a set of string functions (like len(), search(), replace(), format()) but I don't see any case manipulation.

TestStand 2.0.1 does not have these functions, so a code module is the way go. However, it is very likely that these functions will appear in a future version of TestStand.

Is it possible to add custom functions to TestStand, so that they show up in the Expression Browser? That could be a really powerful feature.
