Re: [Bug-apl] Suggested change in rendering of ⎕CR

[Hans-Peter Sorge]

Hi,

this looks more like a comma separated value list ( fds ⎕CSV Array )

fds: field delimiter string like
fds←' ",;≡'

fds[1] ←→ Numeric field quote   -
          alt ⊂'()' or other brackets to output (field)
fds[2] ←→ Character field quote -
          alt ⊂'<>' or other brackets to output <field>
fds[3] ←→ Field delimiter
fds[4] ←→ Record delimiter      -
          alt ⊂'{}' or other brackets to output {f1,f2}
fds[5] ←→ Rank delimiter
          on a separate line.
          One line shape 3,
          two lines shape 4, .....

Just my thoughts.

Greetings
HP
