This looks like AREA3000 exists in your MCPATH and it is
write protected, or no directories in your MCPATH allow
writes by you.

The following comments all assume that you are running the script/command line
invocation as user 'eryan' who has a HOME directory of /home2/eryan:

Your MCPATH should be:


Given your settings for MCHOME and MCDATA this would be:


I am willing to bet that the /home/mcidas/workdata directory is not writable
by you, and there may well be a file named AREA3000 there.

> MCGUI=/home/mcidas/bin
> MCTABLE_READ=/home/mcidas/workdata/MCTABLE.TXT:/home/mcidas/data/ADDESITE.TXT

McTABLE_READ should look like:


NB: the directories are separated by a semi-colon, not a colon!

> MCTABLE_WRITE=/home/mcidas/data/ADDESITE.TXT

MCTABLE_WRITE should be:


> McINST_ROOT=/home/mcidas
> XCD_disp_file=/home/mcidas/workdata/DECOSTAT.DAT

McINST_ROOT and XCD_disp_file only need to be defined for the user

This looks OK for the RTIMAGES dataset.  You can see the dataset definition
for the MYDATA dataset by running the DSSERVE command:

dsserve.k LIST MYDATA

It should look something like:

Group/Descriptor         Type  Format & Range     RT Comment
------------------------ ----- ------------------ -- --------------------
