Type <return> to proceed, S to scroll future error messages,

R to run without stopping, Q to run quietly,

I to insert something, E to edit your file,

1 or ... or 9 to ignore the next 1 to 9 tokens of input,

H for help, X to quit.

? h

The control sequence at the end of the top line

of your error message was never \def'ed. If you have

misspelled it (e.g., `\hobx'), type `I' and the correct

spelling (e.g., `I\hbox'). Otherwise just continue,

and I'll forget about whatever was undefined.
