Hi Robert,

>(Unidata) under Red Hat 9.  I am getting an error similar to what I saw under 
>the previous versions:
>
>IMGREMAP:   Invalid parm - can't get pointer for handle=3

I thought that the problem you ran into previously was that the
remapping itself would give blank space in certain circumstances, not
that handle.c would return an error.  Didn't you grab the initial
release of v2003 and _not_ have this problem?  A quick check of the
imgremap.pgm source shows that it has not changed since April of last
year:

C *** $Id: imgremap.f,v 1.80 2003/04/25 02:20:11 barryr Rel $ ***

I just looked at the handle.c code and see that the error comes when
the input handle is greater than the number in the pool.  It is very
strange that this would fail since the handle in question is 3, and I
believe that the pool has 32.  I will check into this later today when
I get the chance.

Can you give me the invocation for which you got this error?  It would
also be useful if I could get the exact dataset elements (images) you
were using when you ran into this problem.

Very strange.  It is almost like an arry has overflowed stepping on
a parameter somewhere.

What is the compilation environment you used to build imgremap.k?
I am assuming gcc/g77, but I want to be sure.

>Thanks,

I will get back to you when I have had a chance to look into this
in more detail.

Cheers,

Tom
