1         ZLIB version 1.2.8 for AS400 installation instructions
   2 
   3 I) From an AS400 *SAVF file:
   4 
   5 1)      Unpacking archive to an AS400 save file
   6 
   7 On 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 
  17 On 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 
  24 2)      Populating the ZLIB AS400 source library
  25 
  26 On the AS400:
  27 
  28 _       Extract the saved objects into the ZLIB AS400 library using:
  29 
  30 RSTOBJ OBJ(*ALL) SAVLIB(ZLIB) DEV(*SAVF) SAVF(ZLIB/ZLIBSAVF) RSTLIB(ZLIB)
  31 
  32 
  33 3)      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 
  43 4)      Compile and generate the service program:
  44 
  45 _       This can now be done by executing:
  46 
  47         CALL PGM(ZLIB/COMPILE)
  48 
  49 
  50 
  51 II) From the original source distribution:
  52 
  53 1)      On the AS400, create the source library:
  54 
  55         CRTLIB LIB(ZLIB) TYPE(*PROD) TEXT('ZLIB compression API library')
  56 
  57 2)      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 
  63 3)      From the machine hosting the distribution files, upload them (with
  64                 FTP in text mode, for example) according to the following table:
  65

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