That would be excellent. I do think these functions have value and am very glad you've publicized them.

I do have one more question. I'm doing a little internal writeup on these, and included a summary of each function from https://support.microsoft.com/en-us/office/excel-functions-alphabetical-b3944572-255d-4efb-bb96-c6d90033e188#bm25. 40 of the 41 functions are described there, but I can't find DATDIF4 there or by googling for it. That page does have DATDIF. DATDIF4 is definitely the name in SASHELP.

Thanks,
Bruce
