I wonder if StP, or other CASE tools, can provide me with a function
I need.  I would like to be able to follow a variable back through
a C program.  This would involve tracking and showing all the
transformations the variable makes as it is used, passed as a parameter,
changed, initialized, and defined.  This means tracking the logical data 
entities since the name, type, and value would change.

The reason I would like this functionality is for a code coverage
improvement process.  There are tools on the market which are able
to determine coverage and show uncovered code.  What I need is a way
to determine how to execute that uncovered code.  This generally
involves forcing the controlling conditionals to follow a certain
path.  Thus, the variables within the conditionals become critical.

If I could find out how to provide the appropriate test input to
make the data transformations force the appropriate path to be taken
I'd be a happy man.  If anyone knows of such a tool, or has another
methodology for improving code coverage from a tester's, not developer's,
perspective, please respond.

Thanks

The way I look at DSE and ERE is that they are mutually exclusive ways
of defining data.  Since STP keeps a dictionary of all defined data, it
doesn't allow you to define the same data (same name) two different ways. 

I think that allowing both would cause a lot of problems like:
Which one would be correct?  When would you want to use one and when
would you want to use the other?

IDE have to say?
