Code page 310

Code page 310 (CCSID 310), known as "3270 APL Graphic Escape"[1] or "Graphic Escape APL/TN",[2] is an EBCDIC code page used on IBM mainframes to write the APL programming language.[3] It is used alongside Code page 037, with the Code page 310 codes being prefixed by the Graphic Escape (EBCDIC 0x08)[4] control character.[5]
