COMAL corner-Part 2 by Jim Weiler
THE COMAL 0.14 OPERATING SYSTEM
- - - - - - - - - - - - - - - - - -
PREMISE: A COMPUTER IS ONLY USEFUL IF
YOU KNOW ITS OPERATING SYSTEM.
- - - - - - - - - - - - - - - - - -
Your first computer purchase is an
event of great expectations and
equally great disappointments. The
salesman tells you everything it can
do, but when you get it home, you
discover everything you CAN'T make it
do. You may know how to program in
BASIC. You may know assembly code.
What you WON'T know (and this applies
to ANY new computer) is the OPERATING
SYSTEM. The operating system is what
you are using whenever you are NOT
running a program disk or cartridge.
Operating systems are usually not very
helpful-- every time you see SYNTAX
ERROR, that's your operating system
telling you to try again. You will
almost NEVER find an operating system
that will prompt you.
I've been leading up to this: We
will not learn a thing about COMAL
programming in this installment.
Instead, we'll learn something about
the COMAL environment -- enough, at
least, to let us enter, save, and run
programs. THEN we'll be ready to
write our first COMAL programs.
