Hello everybody,

I have inherited some code with macro variables processed within loops. The code is running some regressions, comparing standard deviations, and outputting a 'beta' file, containing regression coefficients.

I have noticed that the code takes longer to run with each iteration, and even hangs at some point.

I have added 'ODS NORESULTS' to my options to eliminate the output to the results window, which seemed to improve the performance a little bit.

I looked at the VMACRO file from SASHELP, but the only global vars created are the ones that loop through, and are needed through out the entire processing. I am not sure how the macro variables are held in memory, but this seems like a memory issue.

Any suggestions/thoughts are welcome.

Thanks, Shukla
