INTRODUCTION TO FORMS DESIGN
EASE OF FORMS DESIGN
5. Current Form X -- Repeat Option = A
Next Form Option = A
Next Form Y -- Repeat Option = A
Form X is repeated and appended until the repeat is terminated. When the first Y form
is displayed, there is no more room for the first X and it is rolled off the top of the screen
and deleted. As new Y forms are appended, the X forms continue to be rolled off and
deleted.
6. Current Form X -- Repeat Option = N
Next Form Option = F
Next Form Y -- Repeat Option = A
Form X remains frozen on the screen as form Y is appended to it. When the screen is
filled, X remains frozen on the screen while the oldest Y form, Y(1) is rolled off to make
room for Y(3). Note that if Y(l) fills the screen below X, it will be rolled off the screen and
deleted when Y(2) is displayed.
Note that the F specification determines what happens when the screen is full, The A
specification determines what happens when the next form is displayed. If an appended
form does not fit on the screen with a frozen form, the freeze specification is cleared and
the frozen form is rolled off the screen and deleted until the entire next appended form
fits.
7. Current Form X -- Repeat Option = A
Next Form Option = F
Next Form Y -- Repeat Option = A
Form X is appended to itself. When the repeat is terminated, the first Y form is appended
to the last X. When the next Y form is displayed, the first Y is rolled off the screen and
