Carsten, Thanks ever so for the examples. They were just what the doctor ordered...... I just shows how much I have to learn. ------------------------- Bryan Dietz 3X Corporation 614-410-9205 "Carsten Flensburg" <flensburg@novasol.dk> Sent by: rpg400-l-admin@midrange.com 04/24/2002 05:11 AM Please respond to rpg400-l To: <rpg400-l@midrange.com> cc: Subject: Re: QtocRtvNetCnnDta Hello Bryan, You're right - the question is to allocate sufficient storage to handle any possible size of the return variable. I normally use one of two techniques in this situation: - If you're able to determine an absolute maximum of the return variable and it is within a reasonable size you could simply allocate (or define) the return variable size using the maximum - If it's not safe or applicable to use a maximum size you could call the API twice - initially with an 8 byte parameter to obtain the actual length available, allocate the storage requested and then call the api again with the full return variable parameter. I'll email you a couple of examples of the API in question privately. Best regards, Carsten Flensburg
