[McIDAS #FJX-773901]: TXT2MD modification



Hi Owen,

Long time no hear.  I hope you are doing well!

Ready...

I remember this.

This is hardwired in the TXT2MD source.  I think I can change this for
you (I have logons on a number of machines in your shop that run the LDM
and other Unidata software), but I need to know which of your machine(s)
you are running McIDAS on (e.g., rainbow.al.noaa.gov, stratus.al.noaa.gov,
etc.).

re:
> thanks

No worries.
