Chris@43
|
7 On the AS400:
|
|
Chris@43
|
8
|
|
Chris@43
|
9 _ Create the ZLIB AS400 library:
|
|
Chris@43
|
10
|
|
Chris@43
|
11 CRTLIB LIB(ZLIB) TYPE(*PROD) TEXT('ZLIB compression API library')
|
|
Chris@43
|
12
|
|
Chris@43
|
13 _ Create a work save file, for example:
|
|
Chris@43
|
14
|
|
Chris@43
|
15 CRTSAVF FILE(ZLIB/ZLIBSAVF)
|
|
Chris@43
|
16
|
|
Chris@43
|
17 On a PC connected to the target AS400:
|
|
Chris@43
|
18
|
|
Chris@43
|
19 _ Unpack the save file image to a PC file "ZLIBSAVF"
|
|
Chris@43
|
20 _ Upload this file into the save file on the AS400, for example
|
|
Chris@43
|
21 using ftp in BINARY mode.

|
|
Chris@43
|
27
|
|
Chris@43
|
28 _ Extract the saved objects into the ZLIB AS400 library using:
|
|
Chris@43
|
29
|
|
Chris@43
|
30 RSTOBJ OBJ(*ALL) SAVLIB(ZLIB) DEV(*SAVF) SAVF(ZLIB/ZLIBSAVF) RSTLIB(ZLIB)

35 _ Edit CL member ZLIB/TOOLS(COMPILE) and change parameters if needed,
|
|
Chris@43
|
36 according to the comments.
|
|
Chris@43
|
37
|
|
Chris@43
|
38 _ Compile this member with:

|
|
Chris@43
|
41
|
|
Chris@43
|
42
|
|
Chris@43
|
43 4) Compile and generate the service program:
|
|
Chris@43
|

51 II) From the original source distribution:
|
|
Chris@43
|
52
|
|
Chris@43
|
53 1) On the AS400, create the source library:
|
|
Chris@43
|
54
|
|
Chris@43
|
55 CRTLIB LIB(ZLIB) TYPE(*PROD) TEXT('ZLIB compression API library')
|
|
Chris@43
|
56
|
|
Chris@43
|
57 2) Create the source files:
|
|
Chris@43
|
58
|
|
Chris@43
|
59 CRTSRCPF FILE(ZLIB/SOURCES) RCDLEN(112) TEXT('ZLIB library modules')
|
|
Chris@43
|
60 CRTSRCPF FILE(ZLIB/H) RCDLEN(112) TEXT('ZLIB library includes')

111 Remember that most foreign textual data are ASCII coded: this
|
|
Chris@43
|
112 implementation does not handle conversion from/to ASCII, so
|
|
Chris@43
|
113 text data code conversions must be done explicitely.
|
|
Chris@43
|
114
|
|
Chris@43
|
115 Mainly for the reason above, always open zipped files in binary mode.
