This is the OS/2 version of Interchange, v4.9.8. The zip contains a 'Readme.os2', the original 'Foundation' demo, Mike Heins's new 'mike' demo, and my new 'hardware' demo, along with the patched source, the pre-compiled cgi executable, and the patch.
NB: - this badly needs updating to v5.4x...

This module 'plugs in' to Interchange and enables payment processing through Protx in the UK, using their 'Direct' product. It also creates a 'Virtual Terminal' within the Interchange Admin UI, which allows you to perform all operations needed for Protx (eg, settlement, refunds, changing a credit card, etc) and keep records of all transactions put through the system. Note: full documentation is included within the module - please read it.
NB A new version for their new API is due in August. (in testing now ..)

Paypal Express Payment Module for Interchange

This module 'plugs in' to Interchange and can co-operate with other standard gateways such as Authorize.net, Protx etc. While this is being used on live sites, it is due to have some extra functions added, eg IPN handling for subscription services, the MassPay bit finished, and various other bits in the Paypal API - mostly half done but not quite ...

Full documentation is in the head - please read it.

This is Apache 1.3.26, built with mod_interchange and mod_ssl for Interchange.

Perl 5.8.0, compiled with crypt and all other defines and modules needed for Interchange.

BerkeleyDB 4.1.25 built with "db1.85 compatibility". Readme, patch, tools included in zip.
This crypt is built from ufc.zip, ie, 'ultra fast crypt'. It contains crypto.lib, crypt.lib, ufc.lib, crypt.exe, cert.exe, ufc.a, crypt.a, and crypt.h.

This updated "which" for OS/2 is very different to the Unix version. It includes searches on the BOOKSHELF (flag '-b', for .inf, .pdf), DPATH (flag -'d', for.*), LIBPATH (flag '-l', for .dll, .lib, .a), C_INCLUDE_PATH (flag '-i', for .h), HELP (flag '-h', for .hlp), as well as the PATH (for .exe, .cmd, .bat files). Flag '-a' lists all instances, flag '-s' lists size and datestamp. Returns date as YYYY.MM.DD. Option '-t' tests for a file's existence: returns just '0' if not found rather than the standard list of the full path (still returns filename if found).
