OLE-GET-DATA

This document covers the following topics:


Description

Reads an embedded object into a Natural variable. It is recommended to define an array of variables that is large enough to hold the object: some objects are at least 10 KB in size. You then get the object by executing this procedure; the second parameter contains the size of the array. The procedure returns the real size being used and a Natural error code other than "0" is returned. To avoid getting this error code, you first query the current size of the object with the OBJECT-SIZE attribute.
