one for each field being defined. Following each FIELDn token are
NAME, TYPE, and SIZE tokens. These tokens are optional
except for the TYPE token, which is required. For example:

The TUPLE keyword is followed by a series of arguments, which
are data items. The number of data items following TUPLE is
the same as the number of fields defined in the preceding
SCHEMA. Numeric data items can be typed in without their keyword,
but other data items (text in particular) must include their
keyword. The matching end brace terminates the TUPLE. The
following is a TUPLE with one text field and two numeric fields:
TUPLE {
TEXT Sample string \EOT\
25 43.671
}
The TABLEDEF keyword takes two arguments, the width and
height of the table. It is optionally followed by a series of tokens
which provide default information for the rows and columns of the
table. It also contains information necessary to parse the formulas
of the table.
