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:
