Hi all,
I thought I read somewhere that IDL 5 removed all
parameter limits, but I can't find it anywhere in
the docs. I see that there are still some limits
imposed:
PROCEDURE DEFINITION : 63 parameters maximum.
FUNCTION DEFINITION : 63 parameters maximum.
These two limits also seem to be imposed on IDL kernel functions
and procedures. For example, CALL_EXTERNAL() is limited to 63
parameters, including the shared image name and entry point name.
COMMON BLOCKS : 64 parameters maximum.
LOCAL VARIABLES : Unlimited ? Compiles with 10,000.
STRUCTURE TAGS : Unlimited ? Compiles with 10,000.
VARIABLE NAMES : Unlimited ? I checked 257 characters, that's plenty :-)
PROCEDURE NAMES : 128 characters, then truncated
FUNCTION NAMES : 128 characters, then truncated
I would say that most of these limits are reasonable,
but I ran across the PRO parameter limit when I was converting
some legacy fortran code over to IDL...
