Data Flow Relationships

The table below describes the intraprogram and interprogram relationships detected by the data flow analysis tools.

Relationship	Definition	Type	Icon	Description
calls	N/A	interprogram	N/A	A parameter passed in a call to another program.
cast	MOVE A TO B with data conversion	intraprogram		A data item moved to a data item of a different type.
common area transitions	N/A	interprogram	N/A	For Unisys 2200 Cobol, a common-storage data area item passed in a call to another program. Perform Unisys Common-Storage Area Analysis must be set in the project verification options.
comp	STRING A ... INTO B	intraprogram		An arbitrary computation. The result is produced by applying complex rules to the argument, such as STRING.
comp+	ADD A TO B	intraprogram		An addition-like operation: ADD, SUBTRACT, or corresponding parts of COMPUTE.
comp*	MULTIPLY A BY B	intraprogram		A multiplication-like operation: MULTIPLY, DIVIDE, or corresponding parts of COMPUTE.
comp@	MOVE ARRAY (IDX) TO A	intraprogram		An operation with array elements.
cond	IF A = B ...	intraprogram		Comparison of data items with a symmetric relationship.
cond*	IF A * X = B ...	intraprogram		Comparison of a multiple of a data item with another data item.
const cond	IF A = 1 ...	intraprogram		Comparison of a data item with a constant.
const.move	MOVE 1 TO B	intraprogram		A constant moved into a data item.
const.comp	ADD 1 TO B	intraprogram		An arithmetic operation with constants.
const.init	03 A ... VALUE 1	intraprogram		A data item initialized by a constant.
DMS records	N/A	interprogram	N/A	For Unisys 2200 Cobol, data communication via Unisys DMS database records.
files	N/A	interprogram	N/A	Data communication via files. Traced only when corresponding JCL, ECL, FCT, or CSD files are verified.
files in jobs	N/A	interprogram	N/A	Data flow in JCL datasets when files is selected.
input port	N/A	intraprogram		A data item in which data is received.
move	MOVE A TO B	intraprogram		A data item moved to a data item of the same type.
network records	N/A	interprogram	N/A	For Unisys 2200 Cobol, data communication via network records.
output port	N/A	intraprogram		A data item from which data is sent.
screens	N/A	interprogram	N/A	Data sent to a screen by one program and received in a screen by another.
screen definitions	N/A	interprogram	N/A	Data flow in screen fields when screens is selected.
start	N/A	intraprogram		The startup item in an Impact pane consolidated analysis.
used	MOVE ... TO A ... MOVE A TO ...	intraprogram		A value assigned in a statement used as an argument in another statement.
