RE: Max length of a VARYING field

I personally would hate this becoming a SYSVAL...maybe a BIF to
determine the string len buffer size?
Just brain storming (or cramping pick one)...



Thanks,
Tommy Holden

Perhaps if this occurs, IBM will control this with a new system value.
Then you
could RTVSYSVAL to initialize your VarLenOffset.

If IBM changes the max length of variable length fields (and DS, and
regular
fields) to 16MB, then I suspect that they will increase the hidden
length
attribute to 10I0 or 10U0. Which would mean "4" would be the, then,
correct
magic number.

Off hand, I can't think of another way to do this, but I would suggest
that IBM
may (should?) introduce along with that field-length increase, a new
built-in
that lets you get the %maxlen() of a variable length field.

Then use a constant... VarFldLenBytes c Const(2) or
some other thingy...then 2 isn't a "magic number" it's pretty self-
documenting what you're doing...

Thanks Tommy - that's what I was thinking about doing. I guess I just
wanted to make sure that there wasn't a %maxlen() or something that I
had
somehow missed seeing.
