⎕AV - Atomic Vector
⎕AV is an ISO/IEC 13751 standard niladic system function which returns the entire character set.
|
||||
| Z is a character vector with 216 (65,536) Unicode character elements, 0 to 65535 or hex values 0000 thru FFFF. |
Because NARS2000 is based upon Unicode (i.e., UCS-2), its Atomic Vector has one element for each possible 16-bit character value. Moreover, the elements of the Atomic Vector are ordered such that, in index-origin zero, ((⌈2⍟⍴⎕AV)⍴2)⊤⎕AV⍳'X' gives the bit representation of 'X'.
See also: Unicode page and ⎕UCS.
Note: ⎕AV is a niladic form system function, you cannot assign a value to it.
