Module Flow Diagrams

Interpreting webflow data

Folowing are the names of routines that have control flow diagrams. The routine names are linked to the location in this page that contains the names of each of the label-routine pairs that have flow diagrams. By following the link, diagrams may be observed on pages that contain information about the flow of control, and the data passed either implicitly or explicitly. The diagram for each module show lines connecting the named module with each of the modules that it can transfer control, along with how the control is passed. The letters above the module getting control are:

C - call

G - goto

S - sequential

J - job

If the rectangle containing the module name has an extra bounding line on the left and right, then the source for the module was not available for analysis, either because it is a library routine, or because the source code was not provided.
Following the diagrams is the supporting data for the module. The supporting data includes

Parameters

Explicit parameters - these are visible parameters consistant with structured languages.

Implicit parameters with calling routines - these are local variables that are either set or used by the decomposed routine and used or set by the calling routines

Implicit parameters with called routines - these are local variables that are used or set by the calling routines, or used or set by the decomposed module, and set or used by the called routines

Local Data Usage - documents local data usage
- U - Used
- u - used before set (could be implicit parameter)
- S - Target of SET
- M - Target of MERGE
- N - referenced in NEW
- n - reference in exclusive NEW
- K - referenced in KILL
- k - referenced in exclusive KILL
- d - referenced in $DATA (not yet implemented)
- F - used as FOR variable
- p - passed to a called routine as explicit parameter
- r - passed by reference
- P - Explicit parameter
- R - Explicit parameter by reference
- @ - Used with indirection
Global Data Usage - same as Local but for global data

Associates - invoked modules
Invoking modules

If your browser is not JAVA enabled, the same information is available in the invoked and invoking modules section. Navigation is possible just as for the JAVA diagrams, but by placing the mouse over the calling or called routine and pressing the left mouse button.
