Richmond, I was actually programming in the 1960s in languages that had ‘go to’
but very few or maybe no other control structures. It was a mess and I made a
great many unnecessary mistakes, admittedly not helped by my lack of training
and experience (none was available where I was working!), the lack of comment
capability in early assemblers and indeed the limited instruction sets in early
computers.
Well, I started with MiniFORTRAN and then FORTRAN IV in 1975 . . . up
to my ears in GOTO statements.
The problem of ‘go to’ is the problem of going back to where you came from:
subroutines (procedures) obviously take that problem away, so ‘go to’ is vastly
different from ‘gosub'.
The difference is something I hadn't reflected on: not having a decent
setup for playing around with BASIC to hand.
Sometimes I wish I could find a way to ship my BBC Micro and its
non-standard monitor over here from my attic in Scotland just so I could
relax in front of a black screen occasionally: it has BBC BASIC on a
ROM chip and the things boots up in the blink of an eye.
*Sheer joy!*

Well, perhaps not exactly 'sheer'.
I would *urge all list-users* who have difficulty recalling *GOTO* and
*GOSUB*, as well as those who are too young to have
"been through the fire" to download Beebem [
http://www.mkw.me.uk/beebem/ ] and give it a go. *BASIC* is
automatically loaded,
one programs with line numbers and as soon as one types *RUN* it
compiles and runs: instant gratification.
Even if nothing else it shows how far things have come with LiveCode!
Richmond.
