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.
