REVERSE
Operator usage Short form
<pattern> reverse rev, `
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.
Example Expansion
1-8 reverse 87654321
1223334444555` 5554444333221
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
When two operators have the same precedence, left to right ordering is followed.
