It was an interpretive routine for the Philco 2000. It allowed expressions written in a notation similar to FORTRAN as input, except that the $ was used instead of the ** for exponentiation. The following commands were available: EQUAT INQT BUGG Record on tape an expression and its name. Rename an expression already on tape. Search the tape for name that is to be "bugged" and delete it. OPEN Remove parentheses from an algebraic expression; it performs the necessary algebraic multiplication, groups identical terms, and sorts them in quasi-alphabetical manner. SBST Substitutes one or more expressions in a given expression. FCTR Factor a given expression with respect to a single variable or powers of a single variable. TRGA Expand a product of sine and cosine functions to a sum of sine and cosine functions of multiple angles. DONE Control word for permitting several independent problems to be processed during the same run. Notice that there is no arithmetic defined, nor is there any facility for loop control or control transfers. Although ALGY apparently never received too much usage or publicity, I consider it a major contribution to the field because it was the first system to try to provide multiple capabilities on a general class of expressions all in one system. In fact, for some ideas, ALGY was a conceptual forerunner to FORMAC." Hardware: - Philco 2000 Philco
