Also note the keyboard had some 55 unique (68 listed per tables above, including comparative symbols but several symbols appear in both monadic and dyadic tables) APL symbol keys (55 APL functions (operators) are listed in IBM's 5110 APL Reference Manual), thus with the use of alt, shift and ctrl keys - it would theoretically have allowed a ...
APL has been standardized by the American National Standards Institute (ANSI) working group X3J10 and International Organization for Standardization (ISO) and International Electrotechnical Commission (IEC), ISO/IEC Joint Technical Committee 1 Subcommittee 22 Working Group 3. The Core APL language is specified in ISO 8485:1989, and the Extended ...
When APL\360 was first introduced in 1968, there were no built-in means by which a user could directly access data from outside of the APL system. Thus, starting in 1969, IBM developed the shared variable facility. [2] Following APL.SV, the IBM VS APL and APL2 program products also supported shared variables, as did the IBM 5100 line of computers.
The programming language APL uses a number of symbols, rather than words from natural language, to identify operations, similarly to mathematical symbols.Prior to the wide adoption of Unicode, a number of special-purpose EBCDIC and non-EBCDIC code pages were used to represent the symbols required for writing APL.
The canonical implementation of rank may be the language J, but it is also available in Dyalog APL, the International Organization for Standardization (ISO) technical standard on Extended APL, and NARS2000. Rank has several different meanings. In general, the concept of rank is used to treat an orthogonal array in terms of its subarrays. [4]
Braj Kachru divides the use of English into three concentric circles. [8]The inner circle is the traditional base of English and includes countries such as the United Kingdom and Ireland and the anglophone populations of the former British colonies of the United States, Australia, New Zealand, South Africa, Canada, and various islands of the Caribbean, Indian Ocean, and Pacific Ocean.
