Are there any free zip programs that will compress a number of mvs text
files which are compatible with winzip.

Use jar files?  Needs JAVA in batch, but I think they can be read by zip.

Try gzip ( GNU.zip).

It looks like infozip only allows you to zip a single file and not to use a
wildcard list which is what I require.

Thanks anyway.

Re: mainframe zip

I ran the following to archive 2 files at once -


> //ZIP EXEC PGM=ZIP,

> 'SEQ.DATASET2.TXT'

and downloaded it to my pc in binary and unzipped it but the resultant files
have no end of line separators and I'm left with files of just a single
line.  Is there a parameter to fix that behaviour.

Check the files... they probably have only newline as line separators.

FWIW, there is a sample program in JZOS (in the IBM Java SDK) that I
wrote called "ZipDatasets" which will create Zip files from/to
datasets, PDS members, etc.
Unfortunately, it suffers the same fate (files are converted from
EBCDIC to ASCII with newlines and not CR/NL ).

You can download the source code, class files, and javadoc from here:

http://www-03.ibm.com/systems/z/os/zos/tools/java/products/jzos/jzossamp.html

This can be run in batch using the JZOS Batch Launcher.  Here are some details:
===

Usage: com.ibm.jzos.sample.ZipDatasets [-t targetEncoding] outfile indsname...
  where:
  -t targetEncoding can optionally specify the codepage name to encode the
  text data as it is written to the Zip file.  If not specified,
  this defaults to ISO8859-1 (Latin/ASCII)
  and outfile is either:
- a Unix file path name: /path/to/some/file.zip
- a dataset name:  //A.B.C
- a PDS member name:  //A.B.C(MEM)
- a DD name: //DD:XYZ
- a DD name and member:  //DD:XYZ(MEM)
  and each (at least one) indsname is either:
- a dataset name:  //A.B.C
- a dataset pattern:  //A.*.D
- a PDS member name:  //A.B.C(MEM)
- a PDS member pattern:  //A.B.C(D*X)
- a DD name: //DD:XYZ
- a DD name and member:  //DD:XYZ(MEM)
- a DD name and member pattern:  //DD:XYZ(D*X)
  // prefixes may be omitted from indsnames 
  All dataset names are assumed to be fully qualified.

Example: Zip several partitioned datasets to a Unix zip file:

com.ibm.jzos.sample.ZipDatasets test.zip sys1.proclib(asm*) hlq.**.jcl

Example: Zip all datasets matching two patterns to a dataset:

com.ibm.jzos.sample.ZipDatasets //hlq.backup.zip payroll.*.data gl.**.dat*

Example: Zip data using DDs and input and output:

com.ibm.jzos.sample.ZipDatasets //DD:ZIPOUT //DD:INSEQ1
//DD:INPDS1 //DD:INPDS2(FOO*)

Eventually found the doc and as a result added the -l parameter which fixed
he problem.  The files now contain CRLF instaed of  LF (or NL or whatever it
is).

Try info-zip.  It works, but is somewhat dated with respect to the newer zOS 
file systems and is a little difficult to setup.

Once up and running it handles text files great.  It will do EBCDIC to ASCII 
conversion just fine.  Then just do a binary download and winzip will handle 
the zip file just fine.

Errr... no.  gzip is something different.  The name was badly
chosen, and the authors have apologized.

But will WinZip handle a tar.Z or a pax.Z?  Wikipedia (which
is always right) says:

http://en.wikipedia.org/wiki/Comparison_of_file_archivers#Reading

... Yes.

Not unless the MVS version is radically different from the OS/2
version. The zip command takes a list of files, and if you are calling
it from the shell then you can use file globbing. With the -@ option
it will take a list of file names from STDIN.

Thanks for letting me know about the list of files option.  That works via
SYSIN in batch.  The next problem I have is that I can't get the zip command
to just treat the file names as names without creating a directory
structure.  For instance, if I have a list of files like so -

H30D.QED.SJE.T47996.SZJRSH.SYSP
H30D.QED.SJE.T47997.SZJRSH.SYSP
The zip command treats the first 4 levels as directories and the zip output
looks like thsi -

Translating to ASCII...
  adding: H30D/QED/SJE/T47996/SZJRSH.SYSP   (in=428)
(out=229) (deflated 46%)
  adding: H30D/QED/SJE/T47997/SZJRSH.SYSP   (in=456)
(out=243) (deflated 47%)
total bytes=884, compressed=472 -> 47% savings
and when I ftp and unzip the archive I get a directory structure created of
the first 4 levels.  I've checked the doc but I can't see any way round
this.  Is there some option I've missed or am I stuck with that behaviour.

What happens if you restore them on an MVS system?
