EQU is an 'Equal To' comparison operator for the IF command
C:\> If "blah blah" EQU "blah blah" ECHO The items match
The items match
C:\> If 123 EQU 123 Echo The numbers Match

EQU 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.
