Panel Plot Issue

[Walsh, Brian J]

Hello,
 
I have an issue with GrADS when I try to plot up a 4-panel chart using
four different models.
 
At the beginning of the script, I open each control file separately,
then I reference them by calling file.1, file.2, file.3, and file.4
 
But I run into problems if, for instance, file 2 isn't available, but
file 3 is.  Since GrADS can't open the second file, it will open the
third file, but think it is the second one since it was the second file
it was able to open.  This means that the incorrect data will be plotted
for a model.
 
Is there an easy way around this.  I have attached my gradscript for
reference.  My thought would be opening each file one at a time within
the called product, but would I have to close it out each time or how
would that work.
 
Any help would be appreciated.
 
Thanks,
 
Brian
