AN OPTIMIZED PRINTER PLOTTING SYSTEM CONSISTING OF COMPLEMENTARY 7090 (FORTRAN) AND 1401 (SPS) SUBROUTINES PART Ⅰ - INSTRUCTIONS FOR USERS

摘要

Complementary subroutines for the IBM 7090 and 1401, easy for the PORTRAIT programmer to use, provide printed plots as part of the normal off-line output. These subroutines are simplified so that no choices must be made and generalized so that choices may be made, by the programmer, of the plotting characters, the scales, the appearance of the grid, the number of curves, and other options. The 7090 routines write information-packed records that are decoded and used by the 1401 routine to produce the plot at full printer speed (6 sec/page). Part I contains a general description of the system and is intended as a manual for the user. Part II (Technical Note D-2175) is a manual for the systems programmer.
