A Programming Language /1500 (APL/1500).
McMurchie, Thomas D.; And Others
APL/1500 is an interpretive time-sharing system that builds upon the array operations and structural integrity of APL (A Programming Language) to allow the implementation of the IBM 1500 Instructional System. This is a revision of the original user's guide supplied with the first release of the APL system for the 1500. This version of APL/1500 features a number of extensions, particularly the light-pen capability and a dynamic file handling system. The file items are of variable length, are randomly accessible, and can be any arbitrary APL array (characters or numbers as a scaler, vector, or matrix). The full APL is implemented on the 1500 system with only minor restrictions, primarily relating to the smaller size of the workspace as compared to the IBM 360 implementation. Other extensions include operation of the special terminal hardware of the 1500, primarily the cathode ray tube (CRT) and the film image projector. (Author/JY)
