You have a list of sales that contains - besides from the item numbers - also headers, subtotals, blank lines and so on. However, you are only interested in the item numbers. Furthermore, you have a file that also contains item numbers, e.g. a catalogue of goods for sale in terms of an Excel file. Let's assume you would like to know which items are not found in the list.
You may write a complete line of your catalogue (e.g. incl. the item name) to the output file or only the item number e.g. for later use in a further run of the program.
You download a catalogue of sales from the internet in terms of a text file containing an item number, name and price. One month later you download the same catalogue again.
Now you whish to know:
Which items are new, which items were deleted, for which items there was a change in price?
1. Start ASCII Key, old version
of the catalogue = "input file 1", new version of the
"input file 2"
2. Determine the column ranges that are to be compared: column range 1: item number, column range 2: price. Mark the column range "price" in both file as "data columns"
3. Start the program, option: "Compare", all output files activated
4. Result: you find the new items in output file 2, deleted items in output file 1, items whose prices have changed in output file 4
5. You save your settings in a "variant" (only possible with the registered version)
The next time you download the catalogue you only have to use the settings stored in the variant!
