TPLAN a table driven planning system
Stephen B. Jaffe · ACM SIGAPL APL Quote Quad · 1983
A general broad based APL system has been developed for the storage, retrieval and analysis of financial planning or accounting type data. It is valuable for the class of problems arising from collecting, organizing and consolidating data according to set formulas or recipes. The system, called TPLAN for T able driven PLAN ning system, has as its foundation three principal tables: a table of line or account names; a table of formulas specifying how each account is to be calculated; and a table of data with one row for each account. TPLAN is an “Open” system that provides the user with a collection of conformable utility functions which operate on the principal tables. The package consists of 52 APL functions which contain an average of 3-4 lines of code.
