START BIT

Tasking Statement

SYNTAX: START BIT task number [,task number]. . .

PURPOSE: To enable a BIT task that has previously been defined with an ON BIT statement.

REMARK S: You can disable the task using the STOP BIT statement. The START BIT statement will start the

last task that was declared by the ON BIT statement.

If you use START BIT without first defining the task with the ON BIT statement, CAMBASIC

cannot know whether a valid task exists. Attempting to start a nonexistent task will usually produce

nonsense errors.

See the Multitasking Chapter for more information.
