ROTATE

The left operand is a pattern of any length. The right operand is an integer (which may

be negative) that is interpreted as a length. Rotate takes the set of elements specified by

<number> from the start of the pattern and moves them to the end. A negative

number takes a set of elements from the end of the pattern and moves them to the

beginning.

REVERSE

This operator takes only one operand, the left operand. That operand may be a pattern

of any length. The resulting expansion is the left operand written backwards.

Precedence Ordering

When several operators are used in an expression, they are evaluated in order of

precedence. That is, some operations are performed before others. The precedence levels

for the pattern language are shown in the following:

• upto, downto, concat

•downup, updown

• repeat, extend, template, interleave,

•permute, pbox

•palindrome
