Problem with ⎕FX

[Blake McBride]

Greetings,

I'm not sure what ⎕FX is doing, but it's certainly wrong.

      ∇abc
[1] 111
[2] 222
[3] 333
[4] 444
[5] 555
[6] ∇
      x←⎕CR 'abc'
      x
abc
111
222
333
444
555
      x[4;1]←' '
      x
abc
111
222
 33
444
555
      ⎕fx x
1
      ∇abc[⎕]∇
    ∇
[0]   abc
[1]   111
[2]   222
[3]   333
[4]   444
[5]   555
    ∇

Why is 333 not 33?

Thanks.

Blake
