I need to find the length of a string (variable actually) in a batch file, does anyone know how to do this simply?

This will do it:
:: Send the length of the variable %MyVar% :: to the variable %length% set #=%MyVar% set length=0 :loop if defined # (set #=%#:~1%&set /A length += 1&goto loop) echo MyVar is %length% characters long!
