Abstract : FORMAT (FORtran Matrix Abstraction Technique) is a digital computer program system for abstraction of large order matrix operations. The system provides for direct coding of matrix problems in simple instruction statements similar to Fortran coding. Basic matrix arithmetic (add, subtract, and multiply), matrix output (printing and/or saving on a master tape), and the capability of adding up to ten user-coded routines to increase program flexibility are the three categories of instruction which are recognized by the system. The FORMAT program consists of three major divisions: preprocessing, execution of the instructions, and post-processing. The pre-processing consists of four sequentially executed phases: the system initialization, the abstraction instruction reader, the matrix data card input, and the instruction assembly program. The execution division reads and interprets the instruction tape one abstraction instruction at a time, sequentially. The final division, post-processing, prints matrices and creates matrix output tapes as specified by the abstraction instructions. (Author)
