Leonid:
Hi, thanks for clarifying this. Just one followup question. You mention above that:
Luckily, many of them are made available in SAS via PROC FCMP as user-defined functions (see section PROC FCMP and Microsoft Excel).

I clicked the PROC FCMP link and in the section PROC FCMP and Microsoft Excel there's a link for: You can view these functions at Excel functions in SAS.
That link took me to the SAS Communities home page. Various searches there didn't yield anything obvious. Do you know what it's trying to point me to?

Thanks,
Bruce
