Update Inventory from a text file

	The expected format (order) for each input line is as follows:
		Part #	
		Min Qty (Sell price qty)
		List price
	with a tab character between each field above.

	You must know the drive and folder and filename for this text file.

	Uncheck options you do not wish to update.

	The inputted price is put into the P1 level price if checked.

	The Min Qty is put into the 'Order in Qtys of' field on the master 
	screen, if checked.

	The Last cost and Avg cost are set to the input price times the 
	multiplier, if they are checked. Rounding is to the nearest cent. 

	Part numbers inputted, but not in the master are ignored.

	Be sure to have a backup of some form BEFORE updating.
