[41/42/..] Micro-challenge: order X and Y by magnitude

[Dave Britten]

This appears to work based on a couple quick tests.

Code:

LBL "MAGORD"
X>Y?
X<>Y
CHS
X>Y?
GTO 01
CHS
RTN
LBL 01
CHS
X<>Y
RTN
END

Tests (y, x -> y, x):
8, 4 -> 8, 4
4, 8 -> 8, 4
-8, 4 -> -8, 4
4, -8 -> -8, 4
-8, -4 -> -8, -4
-4, -8 -> -8, -4
-4, 8 -> 8, -4
8, -4 -> 8, -4
8, -8 -> 8, -8
-8, 8 -> 8, -8
