DESCRIPTION
These functions are interface subroutines, in the library −lf77plot, allowing f77 users to call the plot() graphics routines which generate graphic output in a relatively device-independent manner. The f77 subroutine names are the same as the C function names except that linemod and closepl have been shortened to linemd and clospl . See plot() and plot() for a description of their effect.
Only the first 255 character in string arguments to label and linemd are used.
This library must be specified in the f77() command before the device specific graphics library; for example, to compile and load a FORTRAN program in prog.f to run on a Tektronix 4014 terminal:
f77 prog.f -lf77plot -l4014
See plot() for a complete list of device specific plotting libraries.
