	FORTRAN Arithmetic IF

(as I recall:

	IF (x) 100, 200, 300
...

100		continue
C		negative condition logic here
...
200		continue
C		zero condition logic here
...
300		continue
C		positive condition logic here


	In contrast to a computed GOTO (or BASIC ON...GOTO/GOSUB) which
requires positive integer and selects a destination label based on the
value

	GOTO (label1, label2, ..., labelN) x

BASIC:
	ON x GOSUB label1, label2, ..., labelN
	ON y GOTO label1, label2, ..., labelN
