- 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.
