GTR is a 'Greater Than' comparison operator for the IF command
C:\> IF 100 GTR 50 ECHO its more than 50!
its more than 50!
C:\> If 130 GTR 14 Echo OK
C:\> If "130" GTR "14" Echo OK
GTR will perform a numeric comparison where possible, if you need a string comparison use the == comparison operator.
In addition to integer numbers, hex and octal numbers can also be compared within certain limits.
