include a file

I tried to run your latest REXX entry (Rosetta code task: "include a file") and I got three different errors, one with Regina, another with R4, and also with Personnel REXX (all are the latest versions):

Is the REXX program expected to only be executed by a certain REXX interpreter or only under a certain operating system?   -- Gerard Schildberger (talk) 03:06, 13 September 2015 (UTC)

You need the ARexx BIFs and semantics (they're available in Regina) in order to use this Open syntax. I'm not familiar with any other REXX file I/O. --Idrougge (talk) 03:24, 13 September 2015 (UTC)

Then you'll need to include some sort of statement reflecting the needs of your REXX program so that it can be executed correctly.   You should probably also add a:     {{works|Regina with the option AREXX_BIFFS}} to the REXX section header.   You may also want to add that it ONLY works with Regina REXX.
