updates to Ex is (in US funds) $10 for non-commercial users up to 5 lines, $20
for non-commercial users over 5 lines, and $25 for commercial users, unlimited
lines. For this document, commercial users are defined as any system
requiring pay-for-access of any kind.
The standard registered version of Ex supports up to 25 Volumes and copies up
to 25 files per run; custom versions are available on request for additional
cost. Send registrations to:

*******************************************************************************
Purpose
Ex was designed to copy files off of CD-ROM drives before downloading them.
Works with all external transfer protocols that use a redirection file for
the download list, via the @ character and is host (BBS) software independant.
Ex needs a config file to determine your system setup; default is Ex.Cfg but
can be overridden by the -c command line option.
Operation
Ex tracks and sorts by drive up to 50 files per session, and copies up to 5
files as needed, loads the transfer driver, and deletes the copied files
before returning to the host program. Registered versions copy up to 25
files per session. The errorlevel returned from Ex is whatever the transfer
program exited with. If the file transfer module didn't load, then 255 is
returned. Running Ex with no parameters brings up a blurb screen and exits
with errorlevel 0.
OS/2 or DOS
Ex comes in both native OS/2 32-bit and DOS 16-bit versions. Both versions
use the same config file and utilize a temporary file named Ex.Tmp that is
created in the same directory as the redirection file.
Command line
Ex reads the command line for an alternate config file and the redirection
file. Everything after the config file entry is expected to be a transfer
driver filename and it's associated parameters. Ex reads and, if needed,
rewrites the redirection file. A typical command line is:
Ex [-cConfig.Fil] FZmodem sz -rr @D:\BBS\Node5.Lst
This would tell Ex to read configuration file 'Config.Fil' in the current
directory, then to run FZmodem to transfer files listed in D:\BBS\Node5.Lst.
Example PROTOCOL.CTL entries for Maximus BBS and DSZ:
Protocol Zmodem
[...]
Download Ex Dsz port %P speed %W estimate 0 %b ha rts -Z sz @dsz%k.ctl
[...]
End Protocol
Or, for multi node systems:
Protocol Zmodem
[...]
Download Ex -cEx%k.Cfg Dsz port %P speed %W estimate 0 %b ha rts -Z
sz @dsz%k.ctl
[...]
End Protocol
Config file
The default config file is Ex.Cfg located in the current directory, and
needs only 2 verbs -- CopyDir and Volume. Only one CopyDir is permitted but
up to 5 Volumes (25 in registered version) are supported. A cut-and-paste
example config file is:
; Sample config file for Ex
; (All verbs must begin in first column!)
;
; Where to copy files to ...
CopyDir C:\Temp
;
; Drives that we want to copy from and not download directly off of
Volume P:
Volume Q:
Volume R:\
; Alternate method for CD-ROM servers:
Volume \\Cd-Server\CD-1
Volume \\Cd-Server\CD-2
;
; Maximum limits: 1 CopyDir, 5 Volumes. (Registered version is 25 Volumes)
;
; End of Ex.Cfg
Multi-Node
Ex will run multi-node with either a single config file or a config file for
each node. Ex will only delete the files it copied, so all nodes can share
the same CopyDir directory. Should the same file be downloaded from
multiple nodes simultaneously, Ex will only copy the file once for the first
node that exits to download, the others will still download off of CD-ROM.
This is a safety feature; if EX can't copy a file it leaves the redirection
file unchanged and downloads from CD-ROM will be downloaded from CD-ROM.
