Identify interpreter and version?

[rex]

Is there a way to query whether I am running Dyalog APL and what version?
APL+Win has system functions ⎕SYSID and ⎕SYSVER for this; I'm looking for something similar.

      ⎕SYSID
APL+Win
      ⎕SYSVER
10.3.01  Dec 29 2010 10:32:25  Win/32

(I am a very experienced APL programmer, but new to Dyalog.)

Assuming you'd like to do this under program control, this magical formula will work:

Code: Select all

   '.' ⎕WG 'APLVersion'
 Mac-64  18.2.45405.0  S  Development

This doesn't quite tell you that it's Dyalog, but if this call succeeds, it almost certainly is!
See https://help.dyalog.com/18.2/Content/GUI/Properties/APLVersion.htm

Cheers!

That's fine. Thanks a lot.

These (if they succeed and return the result) should be a guarantee:

      2⊃⎕NPARTS⊃2⎕NQ#'GetCommandLineArgs'
dyalog
      {0::⎕DMX.Vendor ⋄ .}⍬
Dyalog
