The Command Line has the following general format:-
Verb/Qualifier=Value Parameter/Qualifier Parameter
Thus a Command Line consists of a Command Verb, optional Qualifiers that may modify the detailed action of the Verb, and (depending on the Verb) required Parameters. Each Parameter may itself have associated Qualifiers. An example of a Command Line might be:-
PRINT/COPIES=2 FILE1/FONT=TIMES,FILE2/FONT=LONDON
which would cause the specified files each to be printed twice, the first
file in ``TIMES" Font, the second in ``LONDON" Font.
A Command Line is case insensitive, all characters being converted to upper
case before being parsed. Furthermore a Command Line may span several lines
on the terminal screen, continuation being indicated by a ``-" character as the
last significant character of a line (ignoring trailing spaces and comments).
Comments are indicated by a ``!" character, the remainder of the line being
ignored. Multiple Commands Lines may be specified on a single line, separated
by spaces or commas.
