Abstract : It has been found that a 4K DEC minicomputer is insufficient for many worthwhile programming applications. To circumvent this problem FOCAL 1969 has been modified to allow the user whose machine is equipped with a Tennetape Magnetic Cartridge Tape Unit (Model TP 1351) to use the tape as a program storage medium. In this modified version of FOCAL, the FDIS and FADC functions have been deleted as well as the L command and the high speed reader input routine. The command Z now initiates transfer of FOCAL text between tape and core. (Author)
