# is command

The is command temporarily stops execution
of the Proc until a response is provided from the keyboard. Input
is placed into the secondary input buffer. Any existing data at that
location is overwritten. If the pointer is already at the end of the
buffer, the input is appended to the end. The colon is the default
prompt character.

## Syntax

```
is{prompt.character}
```
