I am using rexMatchp to get a value from a cell name.
cell_name = "AN2X2"
rexMatchp("^.*X\\([0-9]*\\)$" cell_name) --> t
How do I get the value stored in the register \( ...\)? Basically, I need to extract the 2 after AN2X in the cell name. In Perl this would be equivalent to the $1 variable, what is it in SKILL?
