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

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