## b Statement

b Statement — This statement resets the clock.

## Description

This statement resets the clock.

## Syntax

    b p1

## Performance

p1 -- Specifies how the clock is to be set.

### Special Considerations

p1 is the number of beats by which p2 values of subsequent i statements are modified. If p1 is positive, the clock is reset forward, and subsequent notes appear later, the number of beats specified by p1 being added to the note's p2. If p1 is negative, the clock is reset backward, and subsequent notes appear earlier, the number of beats specified by p1 being subtracted from the note's p2. There is no cumulative affect. The clock is reset with each b statement. If p1 = 0, the clock is returned to its original position, and subsequent notes appear at their specified p2.

## Examples

Here is an example of the b statement. It uses the file b.csd.
