Hi all,

Is there any SAS function or procedure that cleans up memory space
other than proc datasteps
can be used to delete all temporary files in work library ?

I'm using proc glm to go through more than 1000 variables to do
stepwise selection but
as it goes through all the variables, the real and cpu time increase.
I don't know if this is
a issue with memory but wanted to try dumping memory at some points
without closing SAS.

Is there any other suggestions instead of reducing the number of
variables?

Thanks.

Yoon

PROC DATASETS, I presume you mean, is the procedure you'd use to clean up
temporary work datasets. Why do you want to know a different one?

Memory is not the same as disk space, also... cleaning up disk space won't
help much with memory unless you're running out of disk swap space.

Perhaps you could give more details to the list about your PROC GLM model
and then some of the more well-versed PROC GLMers could help you out then?
