+        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

+Notes:  For AS400 ILE RPG programmers, a /copy member defining the ZLIB

+                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.
