问题解决, 与 fxf258 兄共鉴:
There are certain statements that might cause EG to hang.
For example: EndSAS;
If not, I know we had issues with earlier versions of EG 4.1 that also
caused more general macro/looping code to hang even though
the log showed the code finished successfully.
So, if you don't have ENDSAS; or similar code, then, try applying the
latest EG 4.1 hotfix to see if that resolves the issue.
