FML VIEWS is a mechanism that enables the exchange of data between fielded buffers and C structures or COBOL records. This facility is provided because it is usually more efficient to perform lengthy manipulations on C structures with C functions than on fielded buffers with FML functions. VIEWS also provides a way for a COBOL program to send and receive messages with a C program that handles FML fielded records.

This section explains how to use VIEWS to provide fielded buffer/structure mappings.
