Conversion of an old script

[fabiospark]

I still have a G3 gml with a few simple scripts and variable manipulating commands and I would need to convert them: Do you mind helping me know how to convert them, please?

Here they are:

1) Variable Manipulation Script

if reg23==2 then reg23=0 else reg23=reg23+1 end


2) Put val in reg


And where should I look to easily check the values of my custom variables (reg23, for instance)?

Thanks.
