Local variables

The Locals tab contains local variables for the current process’s currently active thread and stack frame.

For Fortran codes the amount of data reported as local can be substantial, as this can include many global or common block arrays. If this is a problem, it is best to conceal this tab underneath the Current Line(s) tab so it will not update after every step.

Note

Variables defined within common blocks might not appear in the Locals tab with some compilers. This is because they are considered to be global variables when defined in a common memory space.

The Locals tab compares the value of scalar variables against other processes. If a value varies across processes in the current group, the value is highlighted in green.

When stepping or switching processes, if the value of a variable is different from the previous position or process, it is highlighted in blue.

After stepping out of function the return value is displayed at the top of the Locals tab (for selected debuggers).
