! I can't find file `...'.
This often indicates that the file name was mistyped or that
you are not in the correct directory. TeX will wait for you to
type in a file name. If a mistake was made, and you want to abort the
command, you will need to hit ^D which will cause an
``Emergency stop'' when TeX is waiting for you to type something.
! Missing { inserted.
! Missing } inserted.
! Missing $ inserted.
This usually occurs if a command was typed which can only be used in math mode. LaTeX can be allowed to continue, but the output will look strange. The offending command should be put into math mode.
If you cannot figure out what is wrong, give the SIPB office a
call,
or try the
Athena Consultants. The Zephyr help instance is also often useful; see
the document ``Inessential Zephyr'' for more details on using
zephyr instances.
