How to increment variable under DOS?

Question

I\'ve spent the past 3hrs trying to work this out but just couldn\'t find a solution. Here\'s my batch script:

if NOT Exist Counter.txt GOTO START
Type c:\\count         


        

Answer 1

I realize you've found another answer - but the fact is that your original code was nearly correct but for a syntax error.

Your code contained the line

set /A COUNTER=%COUNTER%+1

and the syntax that would work is simply...

set /A COUNTER=COUNTER+1

See http://ss64.com/nt/set.html for all the details on the SET command. I just thought I'd add this clarification for anyone else who doesn't have the option of using FreeDOS.
