Hi João,

OK, this should not be hard.

I am not sure where you got the batch.k script (from the ldm-mcidas 
distribution?),
but it will be a bad idea to use it since the McIDAS routines are likely
using it when trying to run the McIDAS BATCH command.  The reason for this
is that the McIDAS executables are named <function>.k.

In Unidata McIDAS I include two Bourne shell scripts that I encourage people
to use when they want to execute McIDAS commands from the shell or from
cron. If you are using the SSEC distribution of McIDAS, you will not have
these scripts.  Unfortunately right now I am in Cargagena, Colombia in
a workshop, and I do not have access to my McIDAS distribution.  When
I can get to my environment, I will send you the two scripts.

Cheers,

Tom
