Setting Domain-Based Type-Specific Options

The table below describes the Component Maker domain-based type-specific extraction options.

Option Language Description
Maximum Number of Variable's Values COBOL The maximum number of values to be calculated for each variable. Limit is 200. The lower the maximum, the better performance and memory usage you can expect.
Maximum Size of Variable to Be Calculated COBOL Maximum size in bytes for each variable value to be calculated. The lower the maximum, the better performance and memory usage you can expect.
Multiple Pass COBOL Evaluate conditional logic again after detecting dead branches. Because the ELSE branch of the first IF below is dead, for example, the second IF statement can be resolved in a subsequent pass:
MOVE 0 TO X. 
IF X EQUAL 0 THEN
   MOVE 1 TO Y
ELSE/p>
   MOVE 2 TO Y.
IF Y EQUAL 2 THEN... 
ELSE...
Note: Multi-pass processing is very resource-intensive, and not recommended for extractions from large programs.
Remove Unused Assignments COBOL Exclude from the component assignments that cannot affect the computation (typically, an assignment after which the variable is not used until the next assignment or port).
Replace Variables by Their Calculated Values COBOL Substitute the calculated values of variables for the variables themselves. Alternatively, you can print the values as comments.
Note: Notice how the options in Remove Unused Assignments and Replace Variables by Their Calculated Values can interact. If both options are set, then the first assignment in the following fragment will be removed:
MOVE 1 TO X.
DISPLAY X.
MOVE 2 TO X.
Single Pass COBOL Evaluate conditional logic in one pass.
VALUEs Initialize Data Items COBOL Set variables declared with VALUE clauses to their initial values. Otherwise, VALUE clauses are ignored.
