- ZLIB version 1.2.3 for AS400 installation instructions
- I) From an AS400 *SAVF file:
- 1) Unpacking archive to an AS400 save file
- On the AS400:
- _ Create the ZLIB AS400 library:
- CRTLIB LIB(ZLIB) TYPE(PROD) TEXT('ZLIB compression API library')
- _ Create a work save file, for example:
- CRTSAVF FILE(ZLIB/ZLIBSAVF)
- On a PC connected to the target AS400:
- _ Unpack the save file image to a PC file "ZLIBSAVF"
- _ Upload this file into the save file on the AS400, for example
- using ftp in BINARY mode.
- 2) Populating the ZLIB AS400 source library
- On the AS400:
- _ Extract the saved objects into the ZLIB AS400 library using:
- RSTOBJ OBJ(*ALL) SAVLIB(ZLIB) DEV(*SAVF) SAVF(ZLIB/ZLIBSAVF) RSTLIB(ZLIB)
- 3) Customize installation:
- _ Edit CL member ZLIB/TOOLS(COMPILE) and change parameters if needed,
- according to the comments.
- _ Compile this member with:
- CRTCLPGM PGM(ZLIB/COMPILE) SRCFILE(ZLIB/TOOLS) SRCMBR(COMPILE)
- 4) Compile and generate the service program:
- _ This can now be done by executing:
- CALL PGM(ZLIB/COMPILE)
- II) From the original source distribution:
- 1) On the AS400, create the source library:
- CRTLIB LIB(ZLIB) TYPE(PROD) TEXT('ZLIB compression API library')
- 2) Create the source files:
- CRTSRCPF FILE(ZLIB/SOURCES) RCDLEN(112) TEXT('ZLIB library modules')
- CRTSRCPF FILE(ZLIB/H) RCDLEN(112) TEXT('ZLIB library includes')
- CRTSRCPF FILE(ZLIB/TOOLS) RCDLEN(112) TEXT('ZLIB library control utilities')
- 3) From the machine hosting the distribution files, upload them (with
- FTP in text mode, for example) according to the following table:
- Original AS400 AS400 AS400 AS400
- file file member type description

- 4) Continue as in I)3).
- Notes: For AS400 ILE RPG programmers, a /copy member defining the ZLIB
- API prototypes for ILE RPG can be found in ZLIB/H(ZLIB.INC).
- Please read comments in this member for more information.
- Remember that most foreign textual data are ASCII coded: this
- implementation does not handle conversion from/to ASCII, so
- text data code conversions must be done explicitely.
- Always open zipped files in binary mode.
