or not... your background, though without OOP, is pretty good.  C and
assembly and BASIC.  nice mix of experience, and with plenty of
options for today.

If you successfully wrote raw Win16 API then all credit to you!

Many languages are well suited to that without the need to get
involved in precision string-memory management.  perl notably, though
I don't like it all that much myself.  Pascal & BASIC too.  Java has
it too, but....

I read the previous edition (for java 1.1) and thought it was
reasonable too, and noted the volume of pages before 'doing stuff',
but it is aimed at beginners in fairness.   Actually writing file io
programs isn't too involved, but doesn't present the simple
methodology of the others (IMO).

I've done small text io utilities in BASIC, Pascal (Turbo Pascal,
Delphi & Freepascal), those are my choices for that kind of task -
especially delphi because of it's simple filestreams, and the promise
of portability (to Linux).  Freepascal might be worth a look if you're
interested.   Perl advocates can show you some pretty compact scripts
that do pretty large amounts of work though, so check that too.

BASIC, Pascal, Perl - examples for this stuff all over the net.

Various other scripting languages are probably equally good,
familiarity with c will reward you if you go with that.

BASIC, C, Pascal and plenty of others wont force you into oop.

Delphi/Kylix has RAD, there are gui kits for many languages though and
if you were ok with win16 you should be able to pick up.

Isn't that 3.0ghz (remembers reading about in a pc magazine, the new
HT 3ghz P4).  They're all pretty fast nowadays!

Hope comp.programming gives you ideas, a good bet is to try out a few
languages and do some simple file io in each, the one that 'clicks'
with you the most would be good to pursue.
