[IDD #ZAJ-781418]: Imglist set of data exceeding McIDAS count limit



Hi Mary Ellen,

I have been meaning to send you a follow-up email regarding the change
in the maximum size of an ADDE image dataset, but one thing after another
has made me put it off... sorry.

Before I was going to open a ticket with SSEC/MUG, I decided to take a
closer look at the server code that is now limiting the maximum size
of an ADDE dataset to 9999 elements.  What I found convinced me that
the changes that would be needed to get rid of the limitation are more
than what SSEC/MUG are likely to want to take on.  The major issue
comes down to using the maximum number of dataset elements to dimension
an array of strings that represent the fully qualified pathnames to
the elements of the prospective dataset.  If this code were written
in C, then one could realloc the space allotted as needed, but for
some reason the code was written Fortran, so the allocation is static.

One could increase the number of elements allowed, but that would
do nothing more than make the limit a bigger number; it would not
get rid of the fundamental limitation of there being a maximum number.
It is because of this that I don't think that the MUG folks will be
interested in/excited about/willing to make the code change.  I will
informally bounce the notion off of Becky to see if there was a general
consensus that the number of image elements in a dataset should be
limited, or if this was simply something that was never tested because
nobody in SSEC, including the Data Center, has tried to define datasets
with more than 9999 elements.

Cheers,

Tom
