⎕AV

Atomic vector (⎕AV) is the name of a 256-character vector which containes the entire character set of older APL implementations that did not support Unicode, but instead used a single byte to store each character. Its value varies wildly between dialects, and can even differ between editions of the same dialect.

Value

APL2

APL uses two primary values of ⎕AV, an ASCII-based value on personal computers, and an EBCDIC-based value on mainframes. The ASCII-based value is:

      7 32⍴32↓⎕AV
 !"#$%&'()*+,-./0123456789:;<=>?
@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_
`abcdefghijklmnopqrstuvwxyz{|}~?

Dyalog APL

⎕AV is obsolete in Dyalog APL since the Unicode Edition was introduced and is only retained for backwards compatibility.[1] It no longer contains all the glyphs used for primitive functions and operators[2], but can be adjusted by setting the Atomic Vector - Unicode (⎕AVU) variable to a list of Unicode code points. The default value is:

      6 41⍴10↓⎕AV

In GNU APL:
