Understanding Data Flow Analysis

For either Paragraph/Program Analysis or Common Part Analysis, select Perform Data Flow Analysis in the BDF search options to perform an additional test to determine whether similar items perform data flow operations with the same pattern. In data pattern analysis, if item A contains:

MOVE A TO B
MOVE B TO C

and item B contains:

MOVE X TO Y
MOVE Y TO Z

their data pattern is regarded as identical. Whereas if item A contains:

MOVE A TO B
MOVE B TO C

and item B contains:

MOVE X TO Y
MOVE X TO Z

their data pattern is regarded as different.
