PALETTE=<name of a .PAL file>
(specification in GPLOT operation)
determines the color palette for the current graph.
Default directory for .PAL files is the current data path
and secondarily <Survo>\U\SYS .
Each .PAL file is a text file with several lines of the form
<color_index> <Red_intensity> <Green_intensity> <Blue_intensity>
where <color_index> is 0,1,... (max 15 for EGA, for example) and
intensities are integers from 0 to 1000.
The PAL1.PAL file corresponds to the default colors obtained without
any PALETTE specification.
