16、onship of this amendment to ANSI and ECMA Standards It is the intention of this amendment that all programs and implernentations that conform to the Addendum to ANS BASIC, X3.113A- 1989, shall automatically conform to this amendment. In addition to the conformance modules defined in ISO/IEC 10279, t

17、his amendment contains four new conformance modules. Of these, modules p) and r) correspond, respectively, to modules (7) and (8) in the Addendum to ANS BASIC. None of these new conformance modules corresponds to conformance modules in ECMA BASIC, ECMA- 116, inasmuch as ECMA BASIC does not include definitions for individual Character input or for modules. lSO/IEC 10279:1991/Arnd.1:1994(E) CS 35060.00 Descriptors: data processing, programming (Computers), Computer programs, programming languages, BASIC.
