Describe the functions of the debugger screen

- Single step(F5) - Use this option to step through the program statement by
statement. This allows you to branch into subroutines and function modules, and to
execute these routines step by step as well. Once a subroutine or function module
has been processed, control returns to the statement following the CALL FUNCTION
or PERFORM statement.

- Execute(F6) - Use this option to process a program line by line. All of the
statements on the current line are processed in a single step. If you are positioned
on a line that calls a subroutine and you choose Execute, the Debugger processes
the whole subroutine and then moves on to the line following the subroutine call. This
allows you to jump through the statements within the subroutine.

- Return(F7) - The Debugger returns from a routine to the point at which control
returns to the main program. Use this option to return from a subroutine, function
module, or called program to the calling program.

- Continue(F8) - Use this option to process the program up to the next dynamic or
static breakpoint or up to the cursor position. If there are no more breakpoints in the
program and no cursor has been set, the system exits debugging mode and
executes the rest of the program normally.

- Tables - Display the contents of internal tables.
