Chris@4:         ZLIB version 1.2.7 for AS400 installation instructions
Chris@4: 
Chris@4: I) From an AS400 *SAVF file:
Chris@4: 
Chris@4: 1)      Unpacking archive to an AS400 save file
Chris@4: 
Chris@4: On the AS400:
Chris@4: 
Chris@4: _       Create the ZLIB AS400 library:
Chris@4: 
Chris@4:         CRTLIB LIB(ZLIB) TYPE(*PROD) TEXT('ZLIB compression API library')
Chris@4: 
Chris@4: _       Create a work save file, for example:
Chris@4: 
Chris@4:                 CRTSAVF FILE(ZLIB/ZLIBSAVF)
Chris@4: 
Chris@4: On a PC connected to the target AS400:
Chris@4: 
Chris@4: _       Unpack the save file image to a PC file "ZLIBSAVF"
Chris@4: _       Upload this file into the save file on the AS400, for example
Chris@4:                 using ftp in BINARY mode.
Chris@4: 
Chris@4: 
Chris@4: 2)      Populating the ZLIB AS400 source library
Chris@4: 
Chris@4: On the AS400:
Chris@4: 
Chris@4: _       Extract the saved objects into the ZLIB AS400 library using:
Chris@4: 
Chris@4: RSTOBJ OBJ(*ALL) SAVLIB(ZLIB) DEV(*SAVF) SAVF(ZLIB/ZLIBSAVF) RSTLIB(ZLIB)
Chris@4: 
Chris@4: 
Chris@4: 3)      Customize installation:
Chris@4: 
Chris@4: _       Edit CL member ZLIB/TOOLS(COMPILE) and change parameters if needed,
Chris@4:                 according to the comments.
Chris@4: 
Chris@4: _       Compile this member with:
Chris@4: 
Chris@4:         CRTCLPGM PGM(ZLIB/COMPILE) SRCFILE(ZLIB/TOOLS) SRCMBR(COMPILE)
Chris@4: 
Chris@4: 
Chris@4: 4)      Compile and generate the service program:
Chris@4: 
Chris@4: _       This can now be done by executing:
Chris@4: 
Chris@4:         CALL PGM(ZLIB/COMPILE)
Chris@4: 
Chris@4: 
Chris@4: 
Chris@4: II) From the original source distribution:
Chris@4: 
Chris@4: 1)      On the AS400, create the source library:
Chris@4: 
Chris@4:         CRTLIB LIB(ZLIB) TYPE(*PROD) TEXT('ZLIB compression API library')
Chris@4: 
Chris@4: 2)      Create the source files:
Chris@4: 
Chris@4:         CRTSRCPF FILE(ZLIB/SOURCES) RCDLEN(112) TEXT('ZLIB library modules')
Chris@4:         CRTSRCPF FILE(ZLIB/H)       RCDLEN(112) TEXT('ZLIB library includes')
Chris@4:         CRTSRCPF FILE(ZLIB/TOOLS)   RCDLEN(112) TEXT('ZLIB library control utilities')
Chris@4: 
Chris@4: 3)      From the machine hosting the distribution files, upload them (with
Chris@4:                 FTP in text mode, for example) according to the following table:

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