### \settodepth

Synopsis:

```\settodepth{len}{text}
```

Set the length len to the depth of box that LaTeX gets on typesetting the text argument. The length name len must begin with a backslash, `\`.

This will show how low the character descenders go.

```\newlength{\alphabetdepth}
\settodepth{\alphabetdepth}{abcdefghijklmnopqrstuvwxyz}
\the\alphabetdepth
```

If you did not set aside the length len, if for example you mistype the above as `\settodepth{\aplhabetdepth}{abc...}`, then you get something like ‘Undefined control sequence. <argument> \aplhabetdepth’. If you leave the backslash out of len, as in `\settodepth{alphabetdepth}{...}` then you get something like ‘Missing number, treated as zero. <to be read again> \setbox’.
