The control words appearing in the extra specifications of
the GPLOT (PLOT) operations can be defined by the user.
All such definitions are saved in a text file (Survo device
driver) and maintained easily by the SAVEP and LOADP operations
of Survo.
The default device driver for the GPLOT operation is given as
crt_dev=<name_of_file> in the auxiliary file SURVO.APU in the
Survo directory.
Most of the specifications in GPLOT schemes can be given like
GRID=([RED][line_width(2)]),XY
where the driver dependent part has always the form
([...][...]...[...]),
The words in brackets (like [RED] and [line_width(2)]) have to be
defined in the driver.
To override the default driver, use INCLUDE=<name_of_driver>
in your GPLOT scheme.
New drivers can be built by using default drivers as models.
