# PXFUCOMPARE

POSIX Subroutine: Compares two unsigned integers.

## Module

USE IFPOSIX

CALL PXFUCOMPARE (i1,i2,icmpr,idiff)

i1, i2 | (Input) INTEGER(4). The two unsigned integers to compare.
icmpr | (Output) INTEGER(4). The result of the comparison; one of the following values:
-1 | If i1 < i2
0 | If i1 = i2
1 | If i1 > i2
idiff | (Output) INTEGER(4). The absolute value of the difference.

The PXFUCOMPARE subroutine compares two unsigned integers and returns the absolute value of their difference into idiff.
