To get help on any item listed above, when running PHOTON, type the

item name followed by a question mark, e.g. 'CONTOUR OFF ?'. Items

marked with an asterisk (*) give help on selected topics,

and are not PHOTON commands, while items marked (R) refer

to subcommands of the REPLAY command. Commands marked (U)

may only be issued from a USE file.



In help entries, command names are shown thus :-

   CON[tour] ON <element number>

where the minimum abbreviation for the command is shown in

capitals, with the rest of the command in square brackets.

Any abbreviation of the full name down to the minimum will

be accepted. Parameters are shown in angle brackets; the

program will prompt for essential parameters if they are

not given on the command line.
