OK, I'll jump back in on this.  I just left an assignment
(incomplete BTW) updating a Fortan program.  Some of the source was 50% 
GOTOs - no kidding.  Line numbers, too.  

	IF (FRED.EQ.0)  GO TO 124
	IF (BARNY.EQ.1) GO TO 234
	IF (WILMA.EQ.2) GO TO 180 

Line after obscure line. Awful crap.  Life is too short 
to deal with this stuff.

I can confidently say I have never used a GOTO in Ada. Never had to.
