Shared variables have such feature.  Though, it's probably not the right
place for you too look in this case, as shared variables are whole separate
name class and are handled differently than ordinary variables.


But one could even make hackish real-time display without any changes in
interpreter by sharing variable in question and then in another terminal
doing something along the lines of:

      nnnn ⎕SVO 'SVAR'
      0 0 1 0 ⎕SVC 'SVAR'
      SVAR ⋄ →⎕LC  ⍝ print SVAR in a loop every time it's changed

Except that 15×35 array is too big to be shared right now...
