==[ ] (EQUAL[ ])

By using parentheses you can change the sequence of processing

comparative commands in a statement list. The opening-parenthesis

command puts the content of the word accumulator onto the program stack.

This clears the accumulator for calculation of intermediate results.

The closing-parenthesis command gates the buffered value from the program

stack with the content of the word accumulator. The TNC saves the result in

the accumulator again. Maximum nesting depth: 16 parentheses.

Comparative commands cause a direct transition from word to logical

processing. If the specified comparative condition is true, the TNC sets the

logic accumulator to 1; if the condition is not fulfilled, it sets it to 0.

See next page for example.
