Grocery Lister
Version 1.8
October 1991

All Commercial Rights Reserved
* Changes for version 1.8:
- This version primarily fixes a bug which would not allow
the total cost of the grocery list to exceed $99.99. A few
other almost unnoticable cosmetic changes were also made.
* Changes for version 1.7:
- The Current Grocery List window has been changed so that
the grocery list is now displayed in a single column with the
entire grocery item visable. It is also possible to select
this window and scroll through the grocery list using the
window scroll arrows and slider bar.
* Changes for version 1.6:
- The Add, Edit, and Delete Grocery Item dialogs have been
changed to conform more to the GEM standard. Now when
entering a new item, use tab or return to move from the
text field to the price field.
- The Open and Save Grocery File functions have been
rewritten and greatly sped up. As a result of this change,
the disk file format of the grocery file has changed.
Included in the archive is a conversion program (GLD_CONV)
to convert your existing grocery file to the new format.
* Changes for version 1.5:
The primary features added with version 1.5 are command key
equivalents, a sort grocery list command, and a 'jump to
letter' in the grocery file function. Command key equivalents
are shown in the menu to the right of the corresponding
command. The sort grocery list command appears under the file
menu and is described below. The 'jump to letter' feature
allows you to press a key A through Z and jump to the position
in the grocery file where grocery items beginning with that
letter start.
----------------------------------------------------------------
Grocery Lister is a household utility program that allows you to
compile a list of grocery items complete with current price and
total estimated cost. The Grocery Lister can be used to determine
approximately how much you will spend at the store if you know the
items that you need. It can also be used as a budget tool to
allow you to select the items you most need or want if you only
have a fixed amount to spend. With a small amount of database
maintenance work each time you buy groceries you will be able to
maintain a fairly accurate file of the items which you regularly
purchase. This file can be very usefull to remind you of items
which you may need as you compile your grocery list. Finally, for
those who have 'errand boys' do the shopping, the Grocery Lister
will generate a very neat and easy to read printout of the current
grocery list.
To put Grocery Lister to work for you, simply run the program
and use the simple menu commands as explained on the following
pages.
FILE
----
Open Grocery File ^O - Use this command to load a grocery
-------------------- database file into memory. Once
loaded the file may be used to select items for a
current grocery list or it may be edited as desired.
Grocery items can be add to a current grocery list by
moving the mouse pointer over the desired item so that
it is highlighted and pressing the left mouse button.
To increase the quantity of a given item in the current
grocery list, simply click the left mouse button on the
highlighted item to add one to the current quantity
shown. Click the right mouse button on the highlighted
item to subtract one from the current quantity in the
list. A maximum quantity of nine is allowed for any
given grocery list item.
Note: If a grocery list had been previously saved for
the grocery file being loaded, then that list will also
be loaded into memory.
Save Grocery File ^S - Once changes have been made to a
-------------------- grocery file in memory, use this
command to save a copy of the updated grocery file on
disk. If a grocery list existed on disk when the file
was loaded, then it will be updated on disk when the
file is saved. The grocery list will remain saved on
disk until it is deleted as described under 'Delete
Saved List'.
Save Grocery List ^L - The current grocery list in memory
-------------------- can be saved to disk with this
command. Since the grocery file in memory and the
current list in memory are dependant on each other, the
grocery file in memory must be saved to disk before a
grocery list can be saved to disk. If no changes are
made to a grocery file after it is loaded into memory,
then a current list may be saved to disk at any time.
As noted above, when a list is saved on disk, it will
automatically be loaded into memory when its grocery
file is loaded. Grocery files and their grocery list
must remain in the same disk directory.
Delete Saved List - Once a grocery list has been saved
----------------- on disk, it can be deleted with
this command. Again, the grocery file and grocery list
are directly linked. If a grocery list exists on disk
then it will load into memory with its grocery file and
will also be updated on the disk if its grocery file is
changed and saved to disk.
Sort Grocery List ^R - After items have been added to the
-------------------- grocery list, the list can be sorted
in ascending alphabetical order with this command.
Quit ^Q - Exit the program. A warning will be posted if
------- any changes have been made to the grocery file
allowing you to quit anyway or cancel the command.
EDIT
----
Add Grocery Item ^A - This command will bring up a small
------------------- edit window that will allow you to
type in a new grocery item and its price. The item is put
into the grocery file in alpabetical order. The item is
not checked to see if it is already in the file so it is
possible to have duplicate items. To enter the item,
simply type in its name, return or tab over to the amount
field, type in the price in the format shown on the input
line, and press return. The item will be entered into
the file and the input line will be cleared so that
another entry can be made. When finished entering new
items, press return on a blank input line to quit out of
the edit window.
Note: Once an item has been entered into the grocery
file its name can not be changed. If an items name
needs to be changed, it must be deleted from the file
and then added back again.
Edit Grocery Item ^E - This command is used to alter the
-------------------- price of an existing grocery item.
To change an items price, move the mouse pointer over
the desired item so that it is highlighted and then
select the Edit Grocery Item command. Be sure that the
desired item remains highlighted when the command is
selected. The item will be placed in the edit window
with the cursor positioned at the amount input field.
Enter the new price in the format shown on the
input line and press return. The edit window will be
closed and the new price will be updated in the grocery
file.
Delete Item ^D - Use this command to remove unwanted items
-------------- from the grocery file. Position the
mouse pointer over the item to be deleted and then
select this command from the menu line. Be sure that
the desired item remains highlighted when the command is
selected. The item will be placed in the edit window
and you will be asked to verify the delete operation.
Type a 'Y' to confirm the delete or an 'N' to cancel the
command. The left mouse button may also be pressed to
confirm the delete and the right mouse button may be
used to cancel the command.
Clear All ^C - This command can be used to clear both the
------------ grocery file and grocery list out of current
memory. If changes have been made to the grocery file or
grocery list they will be lost. This command does not
effect files saved on disk.
Print
-----
Print Grocery File - Use this command to print out the
------------------ current grocery file in memory. The
file will be printed in continous form with no page
breaks.
Print Grocery List ^P- Use this command to print out the
--------------------- current grocery list in memory.
The list will be printed in continous form with no page
breaks. The printout from this command can be used as a
shopping list and to mark changes in prices while buying
groceries.
Grocery Lister may be freely distributed provided no changes are
made to the program or the documentation. This user manual must
be included with the program if it is to be placed in any public
access medium.
