Help!!!!!!!!!
I am trying to transfer files ("C" source code) between
UNIX (Sun, BSD 4.2) and an IBM system running VM/CMS.
Question #1:
I am looking for a UNIX utility that can create IBM format
tapes on my UNIX system.
With this utility, I can load the tape onto the IBM system,
and read the tape directly into VM/CMS without having to
worry about translation of special characters.
This means that the UNIX utility must create IBM "labeled"
tapes with variable length records in EBCDIC, and be able
to directly translate ASCII files to EBCDIC when writing them
to the tape. In this way, the process of moving files from UNIX
to IBMd would be transparent.
Does anyone know of such a UNIX utility????
(Don't care about cost.....)
Question #2:
The connection between the UNIX and IBM systems is through a dial
up line at 2,400 baud.
What is the best communication package to use in transfering files
between the UNIX and IBM VM/CMS systems?
Is there a version of kermit for VM/CMS that can talk with UNIX?
Appreciate any help in this matter. Thanks....

There is a collection of functions and utilities called "tape-tools" in the AT&T Toolchest. The package is mostly intended to go the other direction - simplify Unix System access to IBM tapes, but it also has a (ksh) shell script that writes IBM labeled tapes using dd. If you know what IBM labels look like, you can build a credible replica of the script by making ASCII `here' documents that look like header and trailer labels and processing them with dd. -- Griff Smith AT&T (Bell Laboratories), Murray Hill Phone: 1-201-582-7736 UUCP: {most AT&T sites}!ulysses!ggs Internet: ggs@ulysses.att.com

Yes, there is a VM kermit and it works nicely with the unix version if you use the appropriate "set" commands to accomodate the half duplex nature of the connection. I use a combination of unix shell scripts, kermit 'take' files, CMS exec files and filename conventions for a crude but working automatic file transfer mechanism. Now, if I could find a file based PROFS mail interface... Les Mikesell

Of course mail works, so does FTP if you put TCP/IP on your IBM system. -Ron

The package is mostly intended to go the other [see above ;-)] I had a similar problem a while ago and was pointed to a package called 'mag' written by Dick Grune, Vrije Universiteit, Amsterdam. If you can't get anything else, let me know, I'll mail it to you. Compressed, it's about 260K. Cheers Mike Schroeder SNAIL: PCS GmbH; Pfaelzer-Wald-Str. 36; D-8000 Muenchen 90; W.

Question #1: >I am looking for a UNIX utility that can create IBM format >tapes on my UNIX system. A program called cmstape which will do this posted to comp.sources.unix a while back. Most VM/CMS sites have utilities for reading OS tapes (only IBM could produce three different tape formats for the same machine!); if you write tapes using something like dd ... obs=800 cbs=80 conv=block,ibm ... and read them with LRECL 80 RECFM FB this might work, although you will lose file names.

You can read ANY tape on VM/CMS if it has physical records that are <= 32760 bytes. Use the following: Mount the tape unlabeled as 181. FILEDEF IN TAP1 (RECFM U LRECL 32760 BLOCK 32760 FILEDEF OUT DISK foo bar a (RECFM U LRECL 32760 BLOCK 32760 MOVEFILE IN OUT This will result in a CMS V-format file with the data from the first file on the tape. Each line of the file is a physical record from the tape. Repeat the filedef of OUT and the MOVEFILE command to read subsequent files. The COPY command does a good job of character conversion. You will need to write a program to look for end-of-lines and rewrite your file. It's not the cleanest solution, but it's cheap.
