Specifies that a listing of the Fortran program is to be
printed out with line numbers. If ftnchek detects an error, the
error message follows the program line with a caret
( ^ )
specifying the location of the error. If no source listing was
requested, ftnchek will still print out any line containing an
error, to aid the user in determining where the error occurred.
Default = no.
