Chapter 7  Using Save Fields and Frozen/Repeating Forms 

The two forms defined so far in the forms file ORDFORM1 allow only a one
line item per order.  In order to allow a number of items to be entered
on a single order, you separate the first form (ORDER) into two forms:
the first, containing header information, is frozen on the screen; the
second, containing one line of order information, is repeated and
appended to the frozen form.  This allows a variable number of parts to
be entered on a single order.

This section also shows how to accumulate the totals for an order into a
save field and then transfer the final total to the TOTALS form.  This
section illustrates the following features:
