I do not use defint32:

IDL> help, i, j
I LONG = 50001
J LONG = 50000

As I remember it, this was added in 8.0, with some bug related to it
fixed in 8.0.1.

Are you sure that it is already in your copy of r_correlate.pro ? This is an ITTVIS supplied program, and it is missing the compile_opt defint32 statement. Note that it is not enough to put compile_opt defint32 in *your* program since the scope is local. You have to edit r_correlate.pro.
An alternative is to use IDL 8.0, where there is automatic promotion of 16 bit integers to LONG. --Wayne

Hi David; I noticed that suggestion in one of your prior posts (I am
an avid follower) and it is in the program already but didn't solve
the issue. :(

I'm not using r_correlate within a loop. I have two files, x and y,
that are 1-D. I am simply using r_correlate(x,y).

You have some code that looks like:
for i=0,50000 do ...
that should read
for i=0L,50000 do ...
Ciao,
