1        ZLIB version 1.2.8 for AS400 installation instructions
2
3I) From an AS400 *SAVF file:
4
51)      Unpacking archive to an AS400 save file
6
7On the AS400:
8
9_       Create the ZLIB AS400 library:
10
11        CRTLIB LIB(ZLIB) TYPE(*PROD) TEXT('ZLIB compression API library')
12
13_       Create a work save file, for example:
14
15                CRTSAVF FILE(ZLIB/ZLIBSAVF)
16
17On a PC connected to the target AS400:
18
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.
22
23
242)      Populating the ZLIB AS400 source library
25
26On the AS400:
27
28_       Extract the saved objects into the ZLIB AS400 library using:
29
30RSTOBJ OBJ(*ALL) SAVLIB(ZLIB) DEV(*SAVF) SAVF(ZLIB/ZLIBSAVF) RSTLIB(ZLIB)
31
32
333)      Customize installation:
34
35_       Edit CL member ZLIB/TOOLS(COMPILE) and change parameters if needed,
36                according to the comments.
37
38_       Compile this member with:
39
40        CRTCLPGM PGM(ZLIB/COMPILE) SRCFILE(ZLIB/TOOLS) SRCMBR(COMPILE)
41
42
434)      Compile and generate the service program:
44
45_       This can now be done by executing:
46
47        CALL PGM(ZLIB/COMPILE)
48
49
50
51II) From the original source distribution:
52
531)      On the AS400, create the source library:
54
55        CRTLIB LIB(ZLIB) TYPE(*PROD) TEXT('ZLIB compression API library')
56
572)      Create the source files:
58
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')
62
633)      From the machine hosting the distribution files, upload them (with
64                FTP in text mode, for example) according to the following table:

107Notes:  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.
114
115        Mainly for the reason above, always open zipped files in binary mode.
