The Sandman's Diskmag Shell
[REVISED VERSION]
Hmm. Well. Yes. What can I say apart from "Oops!". Here's a new version of the
diskmag shell that was given away on the second Kelstar Atari Club program
disk. This program file is a direct replacement of the program file SHELL.PRG
that was in the self-extracting archive. To use it, follow these steps:
[1] delete the original program file SHELL.PRG
[2] copy the file MAGSHELL.PRG off this issue's disk onto the disk where you
had SHELL.PRG.
Here's what's different about this version:
[] printer routines removed as they were faulty. I can't test them myself as I
don't have a printer
[] fixed for different TOS versions with the new STOSFIX routines for greater
compatability.
[] no help screen or screensaver - what you see is what you get. All doc
displayer functions are listed at the bottom of the viewer screen.
[] there is currently no Degas .PC1/PC2 support. Maybe later.
The program runs with exactly the same .INF file, so it's a direct swap of the
two program files with no mucking about. I'm going to keep this .INF file set-
up for all future revisions of this shell, so it'll be a case of simply
copying the latest version over.
THE MISSING LINK
In the original docs for the shell, I whinged on about the Missing Link not
likimg any other extensions being used. Just today (26/April/1997), Bob kindly
passed on a message from Tony Greenwood (gulp!) that this was rubbish - well,
Tony, I totally agree with you, but I did have my reasons for thinking this.
About 3 weeks ago I did a new backup of my compiler disk, and discovered that
there were some dodgy sectors on it, and they were the kind that weren't
totally knackered but accessed okay after 2 or 3 tries. Unfortunately, when
you're compiling in STOS, the compiler only attempts one access then refuses
to go on if it finds an error. I didn't realise there were dodgy sectors
because the drive didn't clunk like it normally does when it encounters them
in GEM, so I wrongly assumed incompatability somewhere in the code. The reason
I assumed the Missing Link was to blame was because the program compiled okay
if I removed certain other extension commands. Now that I'm working with a
100% error free compiler disk, everything works fine, as it should.
So there you go. The problem wasn't the Missing Link, so apologies to all
concerned. The problem was a cross between a STOS compiler bug and a hardware
bug, with the blame lying firmly on my shoulders for not realising what was
going on - I admit I should have checked all possibilities first. Sorry!
