OK, but did he setup the Bourne shell script, batch.k, so that frame 4
is the size you want?

In order for the ROUTE PP BATCH routines to be run with more than
one frame, one has to run 'mcenv' to setup the desired environment.
The first place to check, therefore, is the online help for 'mcenv':

mcenv -- execute in a McIDAS environment
  mcenv [-f <framespec>]... [-e <bytes>] [prog arg...]
Remarks:
  Command line arguments:
     -f <framespec>  specifies a set of frames to include in the
                     McIDAS environment

                     A <framespec> of the form N@LxE in which N, L,
                     and E represent integers, and x is the small
                     letter x, means to allocate N frames of L lines
                     by E elements.

                     A <framespec> of the form LxE means to allocate
                     1 frame of L lines by E elements.

 ...

You can see that the -f flag to 'mcenv' sets the frame size (this is
the setting in .mcidasrc that you modified for the 'mcidas' login).

I just logged onto windfall and see that the -f flag for 'mcenv' in
batch.k (/home/ldma/ldm-mcidas-7.4.0/bin/batch.k) is:

MCPATH=$MCPATH PATH=$PATH LD_LIBRARY_PATH=$LD_LIBRARY_PATH mcenv -f 4@480x640 
$command

This tells you that 4 frames of 480x640 are to be created.  If you want
frame 4 to be 700x872 you need to modify this to:

MCPATH=$MCPATH PATH=$PATH LD_LIBRARY_PATH=$LD_LIBRARY_PATH mcenv -f 3@480x640 
-f 1@700x872 $command

This mod will cause the creation of 3 frames of 480x640 and 1 frame of
700x872.
