Could this be handled automatically?

DEFINE VARIABLE cresponse  AS CHARACTER   NO-UNDO.
DEFINE VARIABLE oMemptr    AS OpenEdge.Core.Memptr NO-UNDO.

oMemptr = New OpenEdge.Core.Memptr().
cresponse = oMemptr:GetString( 1, 30000 ).

The second parameter op the GetString method ensures that the result is < 32000.
