Searches and processes information in multiple prices, i.e. to find minimum value, in compliance with different criteria (coincidence of first symbol or coincidence of word). It is possible to search in one or several selected file. So named "cross-links" are supported, i.e. if the same goods are kept in different price-files, and have a different code, it is enough to assign these two codes as interchangeable and program will keep it mind.
