Cn±x
When labels with consecutive numbers are printed next to each
other across the web, it is done by using a single counter in a
single form.
The command Cn±x in the following example will be used twice
and count up the single counter by one (1) in each position (last
two B-command lines).
Set the Form Step Value p4 to +3 for the counter Cn used in our
example (see the C-command line). Also refer to "C command
– Counter".
