validating the entered data against a set of restrictive parameters, the parameters designed to reduce the likelihood of invalid inventory data;

validating the entered data against a master file, the master file including a list of valid SKU numbers;

displaying an error message if the entered data is not successfully validated against the restrictive parameter and the master file;

storing the validated data in at least one random access memory and in at least oneflash memory;

displaying a report of the inventory in a graphical display.

17 . The method of claim 16 wherein the inventory data is scanned in by a scanner.

18 . The method of claim 16 wherein the inventory data is entered into the computer by a keyboard.

19 . The method of claim 16 further comprising:

entering location information of a merchandise;

entering the SKU number of the merchandise, the SKU number identifying the merchandise;

entering the price term of the merchandise.

20 . The method of claim 16 wherein the restrictive parameters include minimum and maximum restrictions on field lengths and entered values.

21 . The method of claim 16 further comprising sounding an error tone if the inventory data is not successfully validated against the set of restrictive parameters and the master file.

22 . The method of claim 16 further comprising transmitting the entered data to a central computer by an IrDA transceiver.

23 . The method of claim 16 further comprising entering inventory data by a microphone coupled to the computer.

24 . The method of claim 16 further comprising storing validation tables in the random access memory, the validation tables used to validate the inventory data.

25 . The method of claim 26 further comprising connecting the scanner to a scanner interface coupled to the computer.

26 . A method of collecting and validating inventory data by an operator using a portable computer, comprising:

scanning bar codes from merchandise to retrieve the inventory data;

transferring the scanned inventory data into the computer;

validating the inventory data against a set of restrictive parameters, the parameters designed to reduce the likelihood of invalid inventory data;

validating the inventory data against a master file, the master file including a list of valid SKU numbers;

displaying an error message if the inventory data is not successfully validated against the restrictive parameter and the master file;

storing the validated data in a random access memory and in a flash memory;

displaying a report of the inventory in a graphical display.
