Chapter 4 Command-Line Debugging with fdb4 An array of an assumed size can be debugged only for the lower bound of the arrayin a Fortran program.5 The statement label in a Fortran program cannot be debugged.6 In a Fortran program, the breakpoint you can make at the beginning of a proceduremay vary in cases where the -g or --chk option is specified.7 In include files that contain expressions in Fortran, programs cannot be debugged.8 If you want to set a break point in the main procedure which has no program statementin a Fortran program, the break point is set at the first executable statement ordeclare statement.9 When in the Fortran program the continue statement has no instruction, even if youwant to set a break point at this statement, the break point is set at the next executablestatement.Example:integer :: iassign 1010 continuei = 1A break point set at the continue statement will break at the next executable statement(i = 1).10 The index name of the FORALL statement in a Fortran program cannot be debugged.11 In Fortran, a name exceeding 2048 bytes cannot be displayed.12 In Fortran, the value of floating-point registers cannot be set."82 Lahey/Fujitsu Linux64 Fortran User’s Guide
