In this example,
ErrorInHere
reported the error. The
ErrorInHere
procedure was called by
Call1.Call2
, which was in turn called by the main
program. Routine names, such as
Call1.Call2
, indicate a nested routine. If
Pascal cannot find the name of a routine, for example, because the executable
file has been stripped, it prints the hex address.
Using the
-g
Option
If you compile the program with the
–g
option, the traceback also reports the
arguments, the line number, and the file name of each routine.
