Re: Max length of a VARYING field

agreed. it's really another data type.


will it be 16MB large or teraspace large?

How would the compiler handle procedures that return large varying
strings? As I understand it:
d something_ToString...
d pi 32000a varying
d InSomething likeds(refSomething)
/free
return 'abc' ;
/end-free

this procedure will copy 32002 bytes back to the caller despite the
actual varying value being only 3 characters.

Would a procedure that returns a 16meg varying always copy 16meg back
to the caller?

I recall this discussed before as a performance issue. Wasn't the
problem that varying fields are not an ILE (Rochester) supported data
type, but rather a just a compiler construct? Still, it seems this
could be fixed.
