Re: Max length of a VARYING field

This is different from %addr(). When I do %addr(xx)+2 today, it's my way of getting the address of the data portion of the VARYING variable. So %addr(xx:*DATA) makes sense to me in that case.

Heh, we already have %addr(varfld:*DATA) planned for this feature. We had originally considered having %SIZE(varfld:*something); we couldn't think of a decent name for the special parameter, which gave us a strong hint that we were on the wrong track. %addr(x:*data) seems a (much much) more natural way of coding.

Whereas, something like %len(MyVary: *max) (or your suggestion of %varysize() which does the same thing) that would give the maximum amount of CHARACTERS (not bytes) in one fell swoop would be much less ugly.

We hadn't realized until this thread that there was such a need to know the maximum number of characters a field can hold; %len(string:*MAX) is how I would do it, for any string type, not just varying, to avoid having to divide by the character size for ucs2 and dbcs. We'll see ...
