Of course you're right. I was misled by a strong habit I have. When coding
tests, I try to put the notional variable on the left; the notional constant on
the right. I'd code in most other languages:
IF ( CC < 7 )
never:
IF ( 7 > CC )
... but JCL wouldn't allow my habitual:
//STEPA040 EXEC PGM=IEFBR14,COND=(STEP010,LT,7))
or, especially:
//STEPA030 EXEC PGM=IEFBR14,COND=(LT,7)
So I misunderstood:
//STEPA030 EXEC PGM=IEFBR14,COND=(7,GT)
//STEPA040 EXEC PGM=IEFBR14,COND=(7,GT,STEP010)
Where languages allow it, do other programmers generally code
the variable on the left or the right? I find it jarring to see:
IF ( 7 > CC )
(... but my habits were not formed by the syntax of JCL COND or CLI.)
