You can use the WORDSw.
format to print checks with the amount written out below the payee
line.
Negative numbers are
preceded by the word minus. If the number is not an integer, the fractional
portion is represented as hundredths. For example, 5.3 is printed
as five and thirty hundredths. When the value's equivalent in words
does not fit into the specified field, it is truncated on the right
and the last character is printed as an asterisk.
