In Dyalog APL the character vector ⎕AV contains all characters in the Classic Dyalog APL character set. Where can i find information about what each character in ⎕AV stand for? I'm trying to find out what each control character in the ASCII encoding corresponds to in ⎕AV in order to filter out invalid character entered in a form.

  • What exactly do you mean by "stand for" in "what each character in ⎕AV stand for"? Which Unicode code point it has? – Adám Mar 12 '20 at 15:41
  • @Adám Not every character has a meaningful graphical representation. Yes, I mean which ASCII code it has (since I'm only interested in the first 32 ones which coincide with the first Unicode code points). – August Karlstrom Mar 12 '20 at 15:57

Two options:

  1. You can simply apply ⎕UCS to the characters you're interested in.

  2. You can look at the corresponding positions in ⎕AVU.
