Configure the Data Flow Preferences

Configure the colors for duplicate node selection and out-of-date nodes.

Select the type of intra-program relationships that you want to be included in the data flow analysis:

MOVE A TO B (move): A data item moved to a data item of the same type.
MOVE A TO B with data conversion (cast): A data item moved to a data item of a different type.
STRING A ... INTO B (comp): An arbitrary computation. The result is produced by applying complex rules to the argument, such as STRING.
ADD A TO B, et al (comp+): An addition-like operation: ADD, SUBTRACT, or corresponding parts of COMPUTE.
MULTIPLY A BY B, et al (comp*): A multiplication-like operation: MULTIPLY, DIVIDE, or corresponding parts of COMPUTE.
MOVE ARRAY (IDX) TO A (comp@): An operation with array elements.
IF A = B ... (cond): Comparison of data items with a symmetric relationship.
IF A * X = B ... (cond*): Comparison of a multiple of a data item with another data item.
IF A = 1 ... (const.cond): Comparison of a data item with a constant.
MOVE 1 TO B (const.move): A constant moved into a data item.
ADD 1 TO B (const.move): An arithmetic operation with constants.
03 A ... VALUE 1 (const.init): A data item initialized by a constant.

Select the type of inter-program relationships that you want to be included in the data flow analysis:

Calls: A parameter passed in a call to another program.
Screens: Data sent to a screen by one program and received in a screen by another.
Screen definitions: Data flow in screen fields when Screens is selected.
Files: Data communication via files. Traced only when corresponding JCL, ECL, FCT, or CSD files are verified.
Files in jobs: Data flow in JCL datasets when Files is selected.
Network records: For Unisys 2200 Cobol, data communication via network records.
Common Area Transitions: For Unisys 2200 Cobol, a common-storage data area item passed in a call to another program.
Database tables: For Unisys 2200 Cobol, data communication via Unisys DMS database records.

Select these options if you want to trace self-dependencies and/or controlled conditions.

Visualization - check Use curved edges if you want the connecting lines in the Data Flow Graph to have curved edges.
Complexity - set your preferences for a maximum "move" and "usage" node depth.
Colors - specify your preferences for the colors of the graph.
