Sample programs
The following is obsoleted and left for reference only.
Similar sample programs are availabe with the latest version of
GrWin.
ALL the TrueBASIC programs
listed in this excellent text on
simulations in physics have been converted
to C and Fortran77 based on
the GrWin Graphics Library
for graphics.
To execute one of the following sample programs directly from the network,
it is necessary to activate grwnd.exe beforehand or
download grwnd.exe
to a folder passed by the path.
All the files necessary to run the sample programs in the list below are compressed in a
zip file.
