## cggoto

cggoto — Conditionally transfer control on every pass.

## Description

Transfer control to label on every pass. (Combination of cigoto and ckgoto)

## Syntax

    cggoto condition, label

where label is in the same instrument block and is not an expression, and where condition uses one of the Relational operators (<, =, <=, ==, !=) (and = for convenience, see also under Conditional Values).

## Examples

Here is an example of the cggoto opcode. It uses the file cggoto.csd.

Example 118. Example of the cggoto opcode.
