## B Statement

B Statement — This statement adjusts the clock.

## Description

This statement adjusts the clock accumultively.

## 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. The clock is incremented by p1 for subsequent notes.

## Examples

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