Modules Window
If you are using the SUNPro compiler, TotalView can only display module data if you force
it to read the debug information for a file that contains the module definition or a module
function. For more information, see “Finding the Source Code for Functions” on page 225.
Debugging Fortran 90 Modules
Fortran 90 lets you place functions, subroutines, and variables inside modules.
You can then include these modules elsewhere by using a USE command.
When you do this, the names in the module become available in the
using compilation unit, unless you either exclude them with a USE ONLY
statement or rename them. This means that you don’t need to explicitly
qualify the name of a module function or variable from the Fortran source
code.
When debugging this kind of information, you need to know the location of
the function being called. Consequently, TotalView uses the following syntax
when it displays a function contained in a module:
modulename`functionname
You can also use this syntax in the File > New Program and View > Lookup
Variable commands.
Fortran 90 also lets you create a contained function that is only visible in
the scope of its parent and siblings. There can be many contained func-
