increment a variable

[mstinnett]

Is there a way to increment a variable in a batch file such as the way its done in C? (tick++ or ++tick)

Thanks

Two alternatives:

Method (1)

Can be used in a loop or parenthetical expression, or elsewhere:

Code: [Select]

set /a variable+=1
Method (2)

Code: [Select]

set /a variable=%variable% + 1
In a loop or parenthetical expression you must use delayed expansion and

Code: [Select]

set /a variable=!variable!+1
