Summary
editDescriptionIBM 650 student program 1961.agr.jpg |
English: "Student program written in machine language for the w:IBM 650 by me in August 1961. It answers Exercises 6 and 7 on page 23 of Andree, Programming the IBM 650 Magnetic Drum Computer,[1] a popular introductory text.
Exercise 6 asks the student to read a previously discussed deck of punched cards that have a value, X, in the first ten columns and Y in the next ten, and then, for each input card, to punch an output card with the values X, Y, 2X-Y, 2X2-XY, and 2X33 -X^2Y+X in the first 50 columns, ten columns each, with zeros in the rest. Problem 7 asks the student to modify the program to punch a 9 in column 80 if 2X^3 -X^2Y+X is positive. The memory layout and use of SOAP nemonics follows examples given in the text. (I was studying on my own and never had an opportunity to run the program.)"--agr (talk) 15:27, 10 October 2023 (UTC)) |
