Data Entry

CANDAT prompts you for information in the form of a list of choices or tables. Lists are referred to as menus, not to be confused with menus used in restaurants. CANDAT will also prompt you for single field entries as in food codes, date of recalls, etc. An entry of a blank code or a 0 for date will terminate that process.

  1. There are two kinds of menu presented in CANDAT.
    1. The usual menu expects you to make a single choice. That is done by moving the selection bar (cursor) to the choice and pressing the enter key. Another way of accomplishing the same thing is to simply enter the first letter of the choice. Pressing the Esc (escape) key has the effect of choosing the last choice in the menu or of exiting menu selection without making a choice.
    2. The other menu gives you a series of Yes/No choices which you toggle by pressing the Y or N keys. You can also make all the choices Y or all N by pressing the Alt key with your selection of Y or N.
  2. There are two kinds of table entry in CANDAT.
    1. The usual table entry allows you to enter information within each cell of a table. Some cells will only allow numbers, others, both numbers and characters. Whichever is allowed will be obvious from the context. If you try to enter a character and it does not appear in the cell, the cell is probably expecting a number. Blank cells are considered filled with characters and you will not be allowed to move out of the cell until you insert a number. A 0 is usually sufficient. If this entry resulted in an extra line being added to the table, it can usually be removed using Alt F4 (see below). Some of these tables grow automatically as you try to enter another row. Pressing the Enter key in the last cell of the last row of a table activates this feature. You cannot simply move to a row that does not exist by using cursor controls. Other rows can be inserted and deleted in these “growing” tables by using Alt F3 to add lines and Alt F4 to delete lines. To exit after having entered your information, press the Esc key. You can move from cell to cell by pressing Tab (or back Tab) and by using the cursor control keys. You can also use Ctrl Home and Ctrl End to go to the first and last cells respectively.
    2. The other type of table entry allows editing of a full line at a time. This is usually a more “free form” type of entry and you sometimes need to be more careful of the layout of the information in this type of entry. To exit after having entered this information you must press Ctrl E or Ctrl Q. Ctrl E will save your entries, Ctrl Q will quit without saving your entries.
