+//  ZLIB.INC - Interface to the general purpose compression library

+//  ILE RPG400 version by Patrick Monnerat, DATASPHERE.

+//  WARNING:
+//     Procedures inflateInit(), inflateInit2(), deflateInit(),
+//         deflateInit2() and inflateBackInit() need to be called with
+//         two additional arguments:
+//         the package version string and the stream control structure.
+//         size. This is needed because RPG lacks some macro feature.
+//         Call these procedures as:
+//             inflateInit(...: ZLIB_VERSION: %size(z_stream))
