   QTY - This is how many WHOLE units of the ingredient entry
         are necessary for the recipe (e.g. QUANTITY). This
         field will accept up to three NUMERIC characters from
         the keyboard. The BACKSPACE key functions destructively.

   P/Q - This is a fraction of whole units of an ingredient 
         necessary for the recipe (e.g. PARTIAL QUANTITY). IT 
         accepts two separate entries, one for the numerator and 
         one  for the denominator. The numerator responds to all 
         NUMERIC keys. The denominator responds to keys "1"
         through "9",  and "X" ("X" representing SIXTEENTHS).

   UNT - This is the UNIT specifier (e.g. CUP/TSP/BUSHEL... ).
         Use "+", "-", "PgUp" or "PgDn" to select the desired
         UNIT measurement from a predefined list of 55 .
