read is a function, taking a character string as input:

If you need to specify a path, use the forward slash '/' to separate
path components (not '\', which is used to "escape" special characters,
e.g. \n for a carriage return) :


On Windows, if you double-clicked on the gp icon, I think that the path
is relative to the position of the gp.exe binary. For testing purposes,
try to dump a file in that same directory, then read it. (If you're not
on Windows, then the path is relative to the directory you started gp
from on the command line.)

This should work, provided the path is correct.

Same, with forward slash:

  \r examples/bench.gp
