PC-DOS REXX and vDos

[alan]

IBM DOS V7 included a REXX interpreter. It runs successfully under the Nov 2015 vDos release.

It does not run on subsequent releases.  What changed after the Nov 2015 release that caused this situation?

Under the Mar 2020 release I get a popup saying it is a 16 bit application and can't run in a 64 bit environment.

Clearing the popup the code starts to run before ending with an Illegal CPU opcode FF at .....

Seems a component of the REXX package is detected as a Windows program. Passed on to Windows for execution, that then complains it’s actually a 16 bit program.
If REXX is run off a Linux server (or NAS), what when you run it locally?

The REXX version I use is only for DOS. What changed after the November 2015 release. I wondered if it was when 4DOS was removed but it is still present until the August 2017 release.

Could it be you run the program from a network drive, a Linux box/NAS?
If so, what when run you it locally?
