-The '''APL code page''' was used in early implementations of [[APL]] on IBM computer systems and terminals. The original version, [[CP293]], was an [[EBCDIC]]-based character set which replaced many of the characters with the specialized ones needed by the [[APL]] programming language. A later [[ASCII]]-based version was IBM code page 907 ([[CP907]]).

-Internally to APL, characters are assigned code positions within what is known as the "Atomic Vector" (⎕IO), which can differ between systems; one such chart can be found starting on page 201 of the IBM 5100 APL manual (page 207 of [http://bitsavers.trailing-edge.com/pdf/ibm/5100/SA21-9213-0_IBM_5100aplRef.pdf this PDF version]).

 Traditionally, some APL characters with distinct meanings were formed by backspacing and overstriking other characters (originally on a printing terminal). For instance, the "quote quad" is formed by overstriking the "quad" (a rectangular shape) with a single quote. These composite characters now have separate code positions in the Unicode set.
