Robert,

>I found another problem tonight.  UALIST produces no output
>when it should.  Here is output from RAOBRPT for KABQ and 
>below is UALIST, which displays nothing.  I looked in
>makelog and saw no errors. Everything else seems to work fine.

I did some troubleshooting on your system to get to the bottom
of the UALIST problem you reported.  Here is what I found:

o UALIST makes a call to the remote ADDE server which cranks up
  the vpserv server

o when vpserv is compiled with optimization turned on on Solaris x86,
  it dumps core when UALIST requests data

o if vpserv is compiled with either no optimization or with debugging
  turned on, it runs fine

I stared at the vpserv.cp source for quite some time before discovering
that the problem had to do with use of an uninitialized integer variable.
I reported the bug to SSEC; implemented the fix in your copy of
vpserv.cp; recompiled vpserv on your machine; and uploaded the fixed
code to my system so I can include it in the first 7.50 Addenda.

Thanks for letting me troubleshoot this on your machine, and sorry
that I had to do so.

I have not had a chance to look into the ingebin problem we talked about
in a previous email.  I will do so next week.

>Thanks for the help,

Sorry for the problems... (at least this one wasn't mine :^)
