Parameters DSN(file),file
file specifies the name of a file containing the data to be plotted.
It's an ordinary (ASCII) text file created with any text editor (not a word processor !).

Files whose name end with .Z, .zip, .gz are assumed
to be compressed with the standard compress, zip and gzip utilities, respectively.
They are uncompressed "on-the-fly" when read.

These optional parameters, identified by their position in the command string,
