Verify String to See If It's Numerical?

[cpmusick]

I've tried looking in the help file and the forum, but I couldn't find the answer to my question.

Is it possible to make Setup Factory detect if a string is numerical or not? What I'm doing is making it edit a text file. It goes through every line in the file and if it start with a number, it will then change it to something else. However, if it's not a number, then I don't want it to change it.

So, can I make it check to see (on each line) if it's numerical?

Multiply the variable by zero, if it is numeric, the result will be zero.

AssignValue(%IsNumeric%=%CustomVar% * 0)
IF (%IsNumeric% = 0)
The variable was numeric
END IF
