3. DESCRIPTION OF PROGRAM OR FUNCTION

DIAG plots tabulated data. It was developed because of the need for fast graphic representation of a great number of results generated by large computer codes used for safety analyses of nuclear power plants (the RELAP family of codes). DIAG can plot one or more y(x) functions. Each plot is a rectangle into which the function y(x) and optionally the grid are plotted. A title is written on top of the plot. The x and y axes are labeled. Standard plotting routines are used, which makes the program highly transportable.

13. OPERATING SYSTEM UNDER WHICH PROGRAM IS EXECUTED

DIAG was developed on PDP 11/34 with the RT-11 operating system. It was tested on VAX-11/780 under VMS.

[ top ]

14. OTHER PROGRAMMING OR OPERATING INFORMATION OR RESTRICTIONS

DIAG
uses the system-dependent plotting subroutines PLOTS, PLOT, WHERE, NEWPEN, GRID, FACTOR, and SYMBOL which have to be replaced by appropriate routines on different hardware. Some of the coding makes the explicit assumption that the internal representation of characters is ASCII.
