An ASCII notation for APL

Abstract

The increasing use of 120-cps terminals and the growth of APL are placing increasing strains on current APL notation. For those people who think verbally rather than visually, a phonetic notation is preferable to a logographic notation. A notation is proposed for use specifically on ASCII terminals. Specific solutions are offered to the problems of (a) ambiguities in parsing (upper and lower case), (b) recognition of operator sequences (periods as separators), and (c) reserved-word name conflicts (name spaces). The change in notation is accomplished with almost no change to the underlying language.
