Re: Dave McKenzie's UNDELete utility

I compiled the UNDELM program and used SST to change the instruction 3B54 to a value of F86100C8 and ran the program I get nothing back, just a blank record. What am I doing wrong.

Hmmm... let me see.

Actually the source in undelsrc.zip is the RISC source.  However, you
can't just compile it to get a running pgm.  You have to modify a
machine instruction with SST.  (This is what Leif calls "Naughty,
Naughty, Naughty" :-)  But since it's only ONE instruction, maybe it
only deserves one "Naughty".

BTW, I posted the source only for people's curiosity and amusement, at
the request of Gary Guthrie (may he rest in peace).

I originally made the number only 5 digits out of paranoia that people
would tie their machines in knots scanning for billions of records
interactively.  But as I get older, I get more libertarian, so what the
heck!

Let me look into this.

Awesome utility, Dave!

Wondering if it would be possible to increase the number of records that can
be scanned in one shot.  It doesn't seem like it would be a big deal, I
think I saw how it could be done in the CISC-version source, but the RISC
version didn't have the source.

Found the data area that is used to control that, and the 3-byte packed
value.  I upped it from 100 to 99999.  But we're dealing with files with
records in the millions.

I would most appreciate your assistance, if you so choose.
