Hello All

From the following thread https://communities.sas.com/message/140502 I understand that under Windows (in my case Win7 Enterprise 64-bit) the maximum size of a single matrix in SAS IML is 2GB.

I can initialize several 268435448x1 matrices without problems (it seems there is a need for 64 special bits since 268435448=2*1024^3-64).


At the end of the thread it is mentioned that SAS is trying to increase that limit in future releases. I was wondering if there are any news about that? What is the limit in SAS 9.4 and IML 13.1?


I know that I can probably alter my algorithm(s) to work with smaller matrices (probably by thinking a bit about it and using smarter programming or possibly via splitting up the data and iterating), still I am curious and would appreciate if that limit could be increased.

The matrix size limits are unchanged for SAS/IML 13.1, which is the latest release.

That size limit does not apply to SAS/IML 14.1 and beyond. See the article "Large matrices in SAS/IML 14.1."
