Ah, the bad old days. And here I am in a nostalgia thread.

That's a bug. What did it mean? But this is valid:
IF(X)100,200,300
Didn't the expression need to be enclosed in parentheses?

Bug, yes. But easier to do with subroutine formal parameters. I had a
colleague
who wrote a subroutine to generate semilog plots on an impact printer. Once he
wanted a semilog plot. He proudly showed me his accommodation:
CALL LINEAR( 2.718 )
....
SUBROUTINE LINEAR( E )
E = 1.0
RETURN
Voila! Linear! That's actually one of the few things I wouldn't have done.
Some used a shift routine that overwrote its caller with an inline shift
instruction.
