The report on the standard hardware representation for ALGOL 68
Wilfred J. Hansen, H.J. Boom · ACM SIGPLAN Notices · 1977
The A standard hardware representation is desirable for several reasons : * With the exception of square brackets, the set of worthy characters is a subset of most versions of ISO-code, ASCII, and EBCDIC : ISO Standard 646 : 7 bit coded character sets for information processing interchange .An earlier version of this standard was considered in Lindsey, C .H ., "An ISO-code representation for ALGOL 68", ALGOL Bulletin 31 (March, 1970), pp .37-60 (corrected in AB 32 .1 .3) .ANSI, USA Standard Code for Information Interchange (X3 .4-1968),American National Standards -Institute (New York, 1968) .ANSI, American Standard Hollerith Punched Card Code (X3 .26-1970),American National Standards Institute (New York, 1970) {defines a version of EBCDIC} .IBM Corp .,IBM 1403 Printer Component Descry .Lion, Or er no .GA24-3073, 1970 de Hes t e "TN-chain" version of EBCDIC} .Hansen, Wilfred J ., "A Revised ALGOL 68 Hardware Representation for ISO-code and EBCDIC", UIUCDCS-R-73-607, University of Illinois, Urbana (November, 1973) ; revised as "An ALGOL 68 Hardware Representation for ISOcode, ASCII, and EBCDIC" (December, 1974) .0 .Introduction -Third, a single representation convention will promote portable programming .At its September, 1973, meeting in Los This document specifies a minimum Angeles, Working Group 2 .1 of IFIP created a character set that every compiler must Standing Subcommittee for ALGOL 68 Support .The accept and the maximum that may be January, 1975 meeting of this Subcommittee in used in a portable program .
