A METHOD FOR BIT-MAP PARSING USING A COBOL ALGORITHM

摘要

A method for extracting data from bit-map messages (10) using COBOL statements is provided where the messages have one of many possible bit-map (10) combinations by assigning a numeric value for each possible bit-map combination (10); generating a conversion table associating a byte-map )12) for each value; identifying a bit-map (10) within a particular message; converting the bit-map (10) into an associated byte-map (12); and determining, based on the resulting byte-map (12), the absence or presence of the data.
