Decompiling PowerHouse 7.29

[Fry, Mark]

Hi Robert,

Just a slim hope - did you do any debugging with the PowerHouse debugger at
any time?  If so, are there still any .qkl files lying around?  These will
contain the source code for the matching .qkc [possibly including bugs,
too:-)] if you have them.

Of course if you don't have the source for your dictionary, that's easy to
re-create.  Go into qshow and use the 'generate all' command - this will
re-create the dictionary source in a file called qshogen.pdl.  Shame you
can't do the same for Quiz, Qdesign and QTP!

On a different tack, you mentioned you have a unix machine [sorry, I mean
U*ix :-)].  Have you tried to read the tape with the unix dd command, using
the noerror switch?  You might be able to use this to read the contents of
the tape to a file on disk, ignoring bad blocks. (eg dd if=/dev/rmt/0m
of=tapefile noerror).  If you can get this far, you may be able to read the
disk file using tar or cpio [or maybe not], or if all else fails, use sed to
plough through it looking for chunks beginning with SCREEN and ending with
BUILD, writing each one to a different file.

Good luck!

Hi all,

I wrote a fault logging system several years ago that I want to update.
Problem is the DAT it was stored on has a media fault. I've got the
dictionary and compiled files off OK but the sources are unreadable. The
company I worked for at time was taken over and the original HP3000 systems
were replaced by U*ix, therefore the original sources are now gone. Is it
possible to do any form of decompile to enable me in the rewrite of this
system?

FWIW It's good to have access to this list again, got a bit lonely without
it.

regards,
