⎕SYSVER - Return version, compile date, and release target of system

The ⎕SYSVER system function returns

  • the current version of the running system
  • the date and time compiled
  • the execution target.

The result is a character vector with two spaces between each of the three fields.

⎕SYSVER is a niladic function, so it accepts no arguments.

The following is an example from a past release of the interpreter:

      ⎕SYSVER 
0.4.8.12  Thu Jun 12 04:28:56 2014  Win/64 
      ⍴⎕SYSVER 
42

In this example, NARS2000 version is 0.4.8.12, was compiled June 12, 2014 at about 4:30 in the morning, and is the 64-bit version of the interpreter for Windows.


Note: SYSVER is a niladic form system function, you cannot assign a value to it.
