Having trouble getting the files?
Here is some general help on downloading the files from this site and getting them back on an MVS system in a useable state.
The majority of the files were packaged on MVS for transfer using the TSO transmit (XMIT) command to transmit them into a data set. This is done to turn PDS(s) and other odd files into nice FB 80 files which will FTP nicely to PC and UNIX systems. These files are downloaded to a PC and then compressed with PKZIP to reduce the size since we have limited disk space and most people have limited bandwidth to download. Files suffixed .XMI are packaged in XMIT format while there are still a few files here suffixed .DAT that are straight sequential files.
Enter: DA(name.of.your.library) UNIT(unit) VOLUME(volume)
Note: The UNIT() and VOLUME() operands are optional but shown in case your installation puts RECEIVE files on work packs by default like mine does
Most of the content on the site when selected through the web pages downloads using the HTTP protocol which is normally allowed by most firewalls. If you are using an FTP client to directly access the archive you might have trouble downloading if you are behind a firewall.
If you are having trouble downloading from the FTP site try to find out if you are behind a firewall. If you are behind a firewall and you cannot get your network folks to configure it to allow you to download using a web browser try getting an FTP client like WS_FTP that has a few firewall friendly options (PASV mode) that might help. Failing that download from home and email yourself the files or bring them in on a floppy as most are not that large.
FTP clients worth paying for include my favorite WS_FTP Pro from Ipswitch and Blue Zone FTP from SEAGULL Software which is probably worth paying for but is free. You can access this site's files directly by using an FTP client to connect to ftp.cbttape.org but you will miss the news and notes on the web pages.
Some users who upload by FTP have encountered this IBM ProblemPQ29921 FTP to MVS Data Loss
Applicable to OS/ 390 2.7 only
FTP of FB binary to MVS uses double buffering
Only one buffer flushed at end of transfer
Some users have also reported this as a common problem
Some terminal emulation packages or FTP clients which you may use to upload the files default the attributes to VB 255. If you were paying attention above you remember that won't work! The uploaded file must be FB 80. If you have trouble convincing your emulator or FTP client to do this a simple solution is to PREALLOCATE the files using a batch job IEFBR14 or ISPF Option 3.2The errors from RECEIVE can be very misleading and may add to the confusion. So for comparison here is what this looks like. If this is happening to you check and make sure you got the intended attributes on your uploaded file.

Thanks to Mike Cleary and David Alcock from whom I borrowed an outline and a thought or two in writing the above directions. Thanks also to John Hallgren who made suggestions for improvements to this page.
