⎕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, and the execution target. Currently on NARS2000, it returns a 42 character string as indicated below. There are 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
      a←⎕SYSVER
      a
0.4.8.12  Thu Jun 12 04:28:56 2014  Win/64
      '''',a,''''
'0.4.8.12  Thu Jun 12 04:28:56 2014  Win/64'

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.
