- Thank you for trying this first port of ZIP for VM/CMS and MVS!
- Using under MVS:
- ---------------------------
- 1. To use the Info-ZIP's ZIP under MVS you need:
- - C/370 ver 2.1 compiler or another compatible compiler supporting
- long names for function/variable names.
- 2. To compile the program under MVS do :
- - unzip all the files from zip22.zip file. They are stored as
- ASCII format so you have to unzip them first on PC or other
- system that already have UNZIP, and then upload them to the
- mainframe with ASCII to EBCDIC conversion.
- - Copy all the .C files in the PDS called youruserid.ZIP.C
- - Copy all the .H files in the PDS called youruserid.ZIP.H
- - adjust the job ZIPMVSC.JOB to work on your size. Change my
- userid - C888090 to yours
- - execute the job ZIPMVSC to compile and link all the sources.
- - maybe you have to preallocate PDS datasets named:
- youruserid.ZIP.OBJ and youruserid.ZIP.LOAD
- - execute ZIPVMC to compile and link all the sources.
- - if everything is ok you will get an ZIP MODULE
- - the warnings about the duplicated ASCII and EBCDIC symbols
- are OK :-)
- 3. Using ZIP
- - Just read MANUAL
- - A few exceptions concerning MVS
- 3.1. if you want to make a portable zip file that is to be unzipped
- on ASCII based systems use the -a option
- 3.2. If you want to zip the input files as binary ebcdic files
- use the -B (capital letter) option
- 3.3. The date/end the time of the input files is set in the zip's
- dir to the current system date/time
- 3.4. Without specifying the "-a" or "-B" option, the ZIP program
- defaults to "native" (EBCDIC) mode and tries to preserve the
- file information (LRECL,BLKSIZE..)
- So when you UNZIP a file zipped with ZIP under VM/MVS it
- restores the file info.
- There currently some problems with file with RECFM=V*
- I don't save the length of each record yet :-)
- 3.5. No wildcards are supported as input file names:
- So you CAN'T use things like: zip myzip *.c
- 3.6. You can use DD names for zipfilename for example:
- under tso/rexx:
- "alloc fi(input) da('myzip.zip')"
- "zip dd:input file1.txt file2.txt ..."
- under Batch:
- //MYZIP JOB (account)
- //STEP1 EXEC PGM=ZIP,PARM='dd:input file1.txt file2.txt'
- //STEPLIB DD DSN=userid.UNZIP.LOAD,DISP=SHR
- //INPUT DD DSN=userid.MYZIP.ZIP,DISP=NEW,
- // SPACE=(15000,(15000,10000),RLSE),
- // DCB=(LRECL=80,RECFM=F)
- //SYSPRINT DD SYSOUT=*
- Please report all bugs and problems to :
- zip-bugs@lists.wku.edu
- That's all for now.
- Have fun!
