APPLICATIONS MAKER - INSERT and DELETE LINE HELP
The insertion/deletion of a line on the INPUT or REPORT screens is
not quite as simple as it might seem. Also to be considered are the
beginning and ending sub-screen in which to insert the line from the
INPUT screen, and the beginning and ending column in which to insert
the line from the REPORT screen.
The insert/delete line functions act upon a rectangular section of
either screen, or the entire screen. The INPUT screen is divided
into 78 column sub-screens. The width of the input sub-screens is a
known factor, and built into the program.
When dealing with the REPORT, however, you may set the width. This
allows you to use wide-carriage printers, and to use any alternate
pitches that your printer might support. You might choose to use
fifteen characters per inch, and have eight inch wide paper; yielding
one hundred twenty characters of report width.
Most applications use multiple sub-screens on the INPUT screen, and
it is quite possible that you are using multiple reports as well.
So, before you insert/delete a line, be sure that you know the limits
of your desired process. The INPUT will prompt you for the
first/last SUB-SCREEN, and the REPORT will ask for the first/last
COLUMN in which to insert/delete the line.
RANGE VIOLATIONS:
If you are inserting/deleting an item from the first screen and you
have initialized an item that spans the first and second screens the
insert process will be aborted and the line/column of the offending
item will be displayed in an error message.
BLANK INPUT ITEMS:
When inserting/deleting lines on the INPUT screen the program will
automatically update the BLANK INPUT items that act upon the chosen
portion of the screen. If you insert a line these items will be
changed to blank a portion of the screen one line down from their
original value; deleting a line will do the same one line up.
If there are BLANK INPUT items that act upon the first two SUB-
SCREENS, and you attempt to insert a line into only the first screen
the insert will be aborted and the line/column of the offending item
will be displayed in an error message.
