Google "Proc Corr Concepts" or look here:

Statistically speaking, isn't the rule of thumb 10 times the number of
observations to the number of variables in your study?

Subject: Proc CORR running out of memory

Hi SAS experts.

I am getting an out of memory error when I try to run proc corr on a dataset
with 784 observations and 6122 variables. The code is provided below.

Is there a limitation on the size that Proc CORR can handle? I am using SAS
9.1 on Linux.

This is urgent. So a prompt response will be greatly appreciated.

Code used:
----------------

proc corr data=outlib.a outp=outlib.b noprint cov;
run;


Thks
Jayati
