Selective specification with Quad IO fails

[Hans-Peter Sorge]

Hi,

Just a simple test:

      x.y ← 1 2 3
      x.y
1 2 3

      x.y[1]
1

      1⊃x.y
1

      ⎕IO⊃x.y
1
      (⎕IO⊃x.y)←⊂ 'abc'
SYNTAX ERROR+
      (⎕IO⊃x.y)←⊂'abc'
      ^        ^

      (1⊃x.y)←⊂ 'abc'
      x.y
 abc 2 3

Greetings
Hans-Peter
