The general syntax for a EXTREMA command line is:
command\qualifier...\qualifier p1\qualifier p2\qualifier ...
The parameter fields in a command line are separated by commas or blanks. If a field starts with a quote, `, or an opening parenthesis, (, then commas and blanks are considered to be a part of that field, up to the end quote, ', or end parenthesis, ). Character strings are fields enclosed in quotes. For example, the command line:
command\qualifier p1 'a, test line' p3
consists of four fields:
command\qualifier
p1
a, test line
p3
