# Tab Clear (TBC)

<VTSequence sequence={["CSI", "Pn", "g"]} />

Clear one or all tab stops.

The parameter `n` must be `0` or `3`. If `n` is omitted, `n` defaults to `0`.

If the parameter `n` is `0`, the cursor column position is marked as
not a tab stop. If the column was already not a tab stop, this does nothing.

If the parameter `n` is `3`, all tab stops are cleared.

## Validation

### TBC V-1: Tab Clear Single

```bash
printf "\033[1;1H" # move to top-left
printf "\033[0J" # clear screen
printf "\033[?W" # reset tabs
printf "\t"
printf "\033[g"
printf "\033[1G"
printf "\t"
```

```
