Identify interpreter and version?

Postby rex on Sun Jul 23, 2023 3:40 pm

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!

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