| * 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)) | |
