* ZLIB.INC - Interface to the general purpose compression library
*
* ILE RPG400 version by Patrick Monnerat, DATASPHERE.
* Version 1.2.3
*
*
* 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))
*
