log window

ShufeGuoding — Tue, 11 Nov 2014 00:35:20 GMT

When i run a optimization subroutine, the log window is full and pops up the message "Windows is full and must be cleared , Slect" , which makes me click the selection cirle very often. Ifi running the following first

FILENAME OUT DUMMY '/DEV/NULL';

PROC PRINTTO LOG=OUT;

as some people suggest, I will not get the error message when the convergence is not properly achieved. How can i handle that?

Have you looked at some of the "More Like This" posts?

For example: https://communities.sas.com/message/54696#54696

If you want a complete log running in batch is worth considering.

You do not need to print out the intermediate results. It sounds ike you have set the options vector to print a lot of information, such as option[2]=4.

Instead, set option[2]=0. When the oprimization finishes, check the value of the return code. If the return code is postitive, convergence was acheived; if the return code is negative, the optimization did not converge.
