GRAFX - A GRAphics FORTRAN eXtension library for the PC
Distribution Diskette Contents and Installation
README - This file! The files on the GRAFX distribution diskette are:
F77L.LIB - Contains the routines in library format for selective
linking with Lahey F77L V3.0. Created using the Lahey Library
Manager (LM).
LP77.LIB - Contains the routines in library format for selective
linking with Lahey Personal FORTRAN (LP77) V2.0. Created using the
Lahey Library Manager (LM).
XXXX.LIB - Call us. We can provide a library for any PC FORTRAN 77
compiler.
GLNK.BAT - A batch command to link files with the GRAFX library.
GRAFX.DOC - Gives a description of the GRAFX library and general
distribution policy.
NOTES.DOC - Notes for programmers on GRAFX subroutine/function
usage. Notes gives a description of each routine included in the
library with the proper calling sequence.
ACLS.COM - A command which resets to alpha mode if your application
terminates in graphic mode and can't be cleared by the DOS CLS
command.
GRAFCOM.ICL - Include file of named common used by GRAFX routines.
PHYSCON.ICL - Include file of physical constants used by GRAFX
routines.
Several illustrative example FORTRAN 77 programs are included to demonstrate
usage. The sample programs are:
EXAMPLE - a driver for the example routines
LINES - FCNPLT (illustrate line drawing modes)
CSAT - XYPLOT (graphs satellite communication data)
SFIT - MULPLOT (linear least squares fit)
SMOTH - TPLOT (a signal processing low pass filter)
STAT - HIST (histogram of a random number generator)
VIEW9 - illustrates multiple views and mid-level routines
WORM - a digital worm demonstrates using "COLOR" to erase lines
EXAMPLE.EXE - An executable demo of the example routines. (On some diskettes)
EXAMPLE.BAT - compiles, links, and runs the example programs. Invoke with the
library you want to use (e.g. EXAMPLE F77L). The selected library is renamed
to GRAFX.LIB. Delete or rename the execuable to run this batch file.
INSTALLATION Installation should be accomplished as follows:
MD \GRAFX CREATE THE GRAFX DIRECTORY
CD \GRAFX CHANGE DIRECTORIES
COPY/V A:*.* COPY FILES FROM DISTRIBUTION DISKETTE
EXAMPLE RUN EXAMPLE PROGRAM (NOT ON ALL DISKETTES)
EXAMPLE XXXX COMPILE, LINK, & RUN EXAMPLES AND RENAME XXXX.LIB
(where XXXX is e.g. F77L or LP77)
Delete the unwanted libraries/files.
REQUIREMENTS: The library was developed and tested with MS-DOS Version 3.10
and requires a CGA card. The use of an 80X87 numeric coprocessor is optional,
but recommended.
GRAFX is easy to use! If you know FORTRAN, the GRAFX library and examples
provide everything you need to produce plots without mastering a lot of
complex features. GRAFX is ideal for research & development, engineering
prototypes, the teaching of numerical methods, or as part of a mathematical
laboratory. Over 50 FORTRAN 77 callable routines provide: three levels of PC
video graphics interface, access to selected DOS and BIOS services, and direct
access to PC hardware for speed and efficiency.
