Re: Multilines with APL character

[Bill Daly]

I played with this and I have a work around:

      )copy 1 utl
      ⍝ Testing reveals curious string
      t2←⊃utl∆convertStringToNumber ¨ t3←"""
→      1 2 3
→      4 ¯5 6
→      """
      ⍴t3
2
      2⊃t3
4 \xaf5 6
      ⍝ Works with a dash
      t1←⊃{utl∆convertStringToNumber ¨ ' ' utl∆split ⍵}¨"""
→      1 -2 3
→      4 5 6
→      """
      t1
1 ¯2 3
4  5 6
      utl∆numberp t1
1

utl∆convertStringToNumber is a function in my apl-library available at 
https://sourceforge.net/projects/apl-library/
