Release 10.1A: OpenEdge Development:
Progress 4GL Reference

Buffer object handle

A handle to a buffer object, corresponding to an underlying Progress buffer, which can be static or dynamic. An example of a static underlying buffer is one you define at compile time by using the DEFINE BUFFER statement, or by implicitly referencing a table in a 4GL construct such as "customer.cust-num". An example of a dynamic underlying buffer is one you create at run time with the CREATE BUFFER statement.

Syntax

buffer-handle [ :attribute | :method ]

buffer-handle

An item of type HANDLE representing a handle to a buffer object.

attribute

An attribute of the buffer object.

method

A method of the buffer object.
