How about this:
function IsDate pDate, pSysDate
if pSysDate then
put char 3 of the short system dateformat into tDelimiter
else
put char 3 of the short dateformat into tDelimiter
end if
if tDelimiter is in pDate and pDate is a date then return true
return false
end IsDate

This probably matters to no one at all, but SQL does not store dates
with forward slashes. SQL
Again, I would prefer a simple one-liner built-in function. What if
instead of "is a date" returning true or false, it instead returned some
expected outputs like "short, long, internet, seconds, ect.". Something
short and sweet.

This probably matters to no one at all, but SQL does not store dates with
forward slashes. SQL datetime formats look like this:

Old trick I learned in Foxpro. Convert something then convert it back and see
if it is identical.
put 20 into tDate
put tDate into tOldDate
convert tDate to dateitems
convert tDate to short date
return ((tDate is a date) and (tDate is tOldDate))

Exactly! I was elated to find the built-in "is a date" check, because I
really wanted to NOT have to roll my own. I was THRILLED that our lovely
English-like syntax was working FOR me. And then an integer was accepted
as a legit date. I didn't like that at all. Why can't t

Yeah. Unless you require a year or something, that'd work.

Yes, it seems to work with any numeric date now.
It *does* think 99/99/00 is a date, though.
Ah. I didn't test that.

What about this from the Master Library from Ken Ray?

isDate("10/10/2001")

Determines if the container passed to it in contains a valid

put "11/20/2017" is a date

put "10" is a date

put "raccoon" is a date

WHY is "10" seen as a date?
