Trace Into (F7)
The Trace Into command runs your program statement-by-statement. When it
reaches a procedure call, Trace Into executes each statement within the
procedure.
(Run│Step Over executes the procedure as a single step).
If the statement DOES NOT contain any calls
to procedures accessible to the debugger,
Trace Into stops at the next executable
statement.
If the statement DOES contain a call to a
procedure accessible to the debugger, Trace
Into halts at the beginning of the
procedure's definition. Subsequent Trace
Into or Step Over commands run the
statements in the procedure's definition.
When the debugger leaves the procedure, it resumes evaluating the statement
that contains the call.
