Stepping Into A Subroutine
The Step Into command allows you to trace the execution of the program one step at
a time and so isolate any bugs that might be present.
When you Step Into a subroutine call, the Program Counter moves to the start of the
subroutine and displays the relevant code. At the end of the subroutine you will be
returned to where it was called from.
At Assembler level a debugging step is the execution of a single instruction.
If you wish to use the Step Into command at Source level you must make the Source
Pane Active. In this case, one line at a time will be executed in each step and any
subroutines or calls within that line will be stepped into.
4 To Step Into a subroutine during debugging:
1.
Select the Debug menu from the Menu bar.
2.
Choose the Step Into option from the menu.
Note: Alternative ways of Stepping Into a subroutine are to use the Step Into icon
on the Unit toolbar (at the bottom of the Debugger window) or to press
F7. Note that it is possible to use the Step Into icon for a non-Active View.
