LEX- Contd
The first part contains the dimensions of certain tables
internal to lex - also may contain definitions of text replace-
ments. It can also contain global C code preceded by a line
beginning %{ and ending with %}
The third part contains C code which is used as us. It usually
contains functions which the second part uses.
The first separator (%%) is essential, whereas the second
separator (%%) is not needed if the third part is empty.
