Hi,
About the true/false thing, I always use 0 and 1 but I was chastised
about that by a colleague recently, that it might not be completely
cross-platform, and now I stutter on it every time I do that,
wondering if I'm not really following a best practice
I seem to recall this same topic
And then there's the query language:
Suppose INVOICED field is supposed to be true or false. Stored as 1 or
0, but maybe left null in some records (We've all been there.):
SELECT CUSTOMER WITH INVOICED
If INVOICED is 0 or null, will said CUSTOMER record be selected or not?
UV selects
Hi,
The query processor defines WITH fieldname that has no relational operator as
a test for non-null so this is not the same as a
true/false test. Again, as far as I know, this is the same across all
multivalue products.

UniData treats WITH fieldname as the equivalent of WITH fieldname .
Both 1 and 0 would be selected, the empty string would not.

There is only one truth, and it's false (0 or ).

On this sidethread, like a true hacker I poked rather a lot at the Ultimate

I discovered that the groupid was embedded in that variable, if you walk it
byte-by-byte
So I was able to use that to show the users, on a BASIC SELECT how *far* the

Hi Wil,
That indeed was my code - ten years old now!
I think I read the same article as Kevin. I don't use it in my day to day
programming (which is in Universe and QM, thus using @TRUE and @FALSE) but I
think I still would use it for Pickwiki. Just a style thing - de gustibus non

Hi Tony,

people's code! You wouldn't be trying to yank Will's chain, would
