Re: gnubol: refmod again

"The subscript can be represented either by an integer, a data-name which
references an integer numeric elementary item, or an index-name associated with
the table. A data-name or index-name may be followed by either the operator +
or the operator - and an integer, which is used as an increment or decrement,
respectively. It is permissible to mix integers, data-names, and index-names."

See page V-38 of the standard also.

So basically it is
a [+|- n]
OR
n

This matches "foo + 0" but no more.

But "+ 1" does not match this. "+1" would. By the way more general expressions
are allowed as function call parameters. So you get treasures such as

function max (a (b) )

Is this two parameters "a" and "(b)" or one "a (b)". Does the ambiguity matter if
a is an array or not?
