+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!
