Report for COMP1100 Assignment 5; A Simple Stock Control Application.

1.            Starting Column, Max Columns

   Itemcode:        1        ,      8
   Description:     11       ,      11
   Wholesale Price: 23       ,      10
   Retail Price:    33       ,      10
   Quantity         43       ,      8

2. The 'or else' checks to see if the stocklist itemcode matches the one
   inputed into the routine.  If it does match then the loop will be 
   terminated and the correct itemcode will be the loop index variable    'i'.

3. - Loop through the items in the stocklist array.
   - For each item, add the product of the quantity in stock and the
     wholesale price, to a variable sum.
   - Print the sum out to the screen

4. STD_FILE_READ - 1
   STORE_ITEM    - number of products in stocklist

5. STOCK_CONTROL
     CLIENTS: 
          - none
     SUPPLIERS: 
          - ARRAY[STORE_ITEM]
          - STRING
          - CHARACTER
          - STD_INPUT_OUTPUT
          - STD_FILE_READ
          - STORE_ITEM
          - INTEGER
          - REAL
   STORE_ITEM
     CLIENTS:
          - STOCK_CONTROL
     SUPPLIERS:
          - INTEGER
          - STRING
          - REAL
          - STD_INPUT_OUTPUT

6. You would have to change the input from an INTEGER to a STRING.
   Then change the 'or else (stocklist.item(i).itemcode = icode)' to
   'or else (stocklist,item(i).description = desc)' where desc is the
   variable inputted into the routine.

OPTIONAL PROGRAM
================

I added a section in the new_item routine to check if the retail price
is higher than the wholesale price.  If it is, the user is prompted to
either continue with the prices unchanged or to re enter the wholesale
and retail prices.  

For the item_report, sell_item and receive_delivery routines I added
sections to check if the itemcode entered actually exists.  If so, the
user is prompted to either return to the menu or re-enter the itemcode.

A save function was added to the main menu.  The user is prompted for
a file name to save to and then the stocklist data is saved to that file.
