# wakeup statement

The wakeup statement is used for BASIC programs to wake up a
 different process that is either sleeping or waiting for input at an INPUT
 statement (which has an associated ELSE clause).

## Syntax

```

 WAKEUP process.no THEN/ELSE ....
```

## Description

When the specified process wakes up, it executes the next statement in that program. If
 the specified process was waiting for input, it takes the ELSE clause of the
 INPUT statement. In either case, SYSTEM(0) can be used to
 determine which process woke it up.

 If the specified process cannot be woken up, the controlling program takes the ELSE
 clause of the wakeup statement. SYSTEM(0) advises as to the reason
 why the process could not be woken up.Note: If called from the THEN clause, SYSTEM(0)
 will not contain relevant information.
