Erick,

Fair enough.

Right you are.  IRIX 5.3 is fairly old now.  The current release of
IRIX is 6.5.

Yes.

>2.  Will version 5.x.x work correctly with McIDAS 7.4?

Yes.  The LDM really has nothing to do with McIDAS per se; it moves data
from place to place and can run user selected programs upon receipt of
products.  The connection to  McIDAS is by:

o running ldm-mcidas decoders; these work fine from all of the LDM releases
o running McIDAS ROUTE PostProcess BATCH invocations; this is accomplished
  by running a substitute for the McIDAS BATCH command which, in turn, sets
  up a McIDAS environment in which the real McIDAS BATCH command runs.  This
  works fine for McIDAS-X 7.x.

>3.  I am already running LDM 5.0.  Assuming that the answers to 1 and 2
>    are "yes" is it worth my time to upgrade LDM now?

Yes it is.  There have been several bugs fixed since the 5.0 release of the
LDM.

>Thanks for your help

You are welcome.
