My hobby website was running the 32-bit mod_rexx on a Windows XP SP3 since mid of 2006.
Towards mid of 2021, I began to have problems keeping the site up for longer than just a few visits between restarts.
Earlier this year (2022), I moved the site to 64-bit PC. It is now running Mod_Rexx/2.4.0 Apr 22 2021 13:44:37 | Open Object Rexx 5 2021-12-30 | Microsoft Windows 10 Pro (which you can see close to the bottom of the landing page when you visit the site).
I understand the confusion about mod_rexx, consider the following...
--> showing Package: Mod_Rexx, Version: 2.1.0, Copyright (C) W. David Ashley 2004.
--> showing Updated /mod_rexx/2.4.0/mod_rexx-2.4.0-x86-64.zip both 6 months ago and 1 year ago
Then, when you see what I stated above, my website is running Mod_Rexx/2.4.0 Apr 22 2021 13:44:37, possibly because the downloaded version had an issue which I fixed (and posted in this group, so I believe).
--> showing version 2.4.0 posted on 2022-01-17, with version 2.2.0 posted on 2007-05-16
Lastly, FYI, since my older codes made (much) use of Mark Hessling's excellent REXXSQL routines (to access various databases, see his website http://www.rexx.org/
), I have to use another version of OORexx now (on the same box), i.e. a 32-bit version 4.2.0 2014-02-22.
Hope this helps.
