Debugging programs when the source files have moved
Having the full path of the source files that make up an application has
the great advantage that it can be debugged in a directory that does
not contain source files. It also means that source files can be
located in more than one directory. It does, however, have the
disadvantage that if the source files move (either because of a drive mapping
change or even debugging the code on a different machine) then the source files
cannot be found. The debugger allows you to specify a path (or list of paths)
down which the debugger can look if it cannot find a source file in its
This path can be specified in two different ways:
1. You can use the /SOURCEPATH command line option when running the debugger.
This should be followed by the path(s). e.g.
... /SOURCEPATH s:\src;s:\src\nt
Here two paths have been given and they will be searched in order. This option
can be shortened to /SP.
2. You can use an MSDOS environment variable called SOURCEPATH that will
be used in the absence of a /SOURCEPATH option. e.g.
