[daip] FIXBX failure.

[R. Craig Walker]

I want to try a different image size.  I use a BOXFILE so I thought
I'd try to use FIXBX to translate it. I didn't get far.  It sounds
like it couldn't find the input data file.  Immediately after the
failure, I did an IMH and the file is there:

>go fixbx
FIXBX1: Task FIXBX  (release of 31DEC16) begins
FIXBX1: REQUESTED DATA NOT FOUND IN CATALOG DIRECTORY
FIXBX1: Purports to die of UNNATURAL causes
FIXBX1: localhost    31DEC16 TST: Cpu=       0.0  Real=       0

Here are the inputs:

I looked in FITBX.FOR.  That message comes out if CATDIR returns something
other than 0.  I imagine CATDIR gets used everywhere, so something is
likely wrong with the inputs FITBX is sending it.  Whatever is wrong,
I don't think is something I can control since IMH works.

I guess I need to add 512 to a lot of numbers by hand.

Cheers,

Craig
