Some Fortran compiler switches automatically set KAP command switches or alter the default KAP switch settings.
Explicitly calling the compiler switch -assume=accuracy
causes KAP to be called with -roundoff=0 . Otherwise,
the KAP command switch -roundoff defaults to
-roundoff=3 .
Explicitly calling the compiler switch -nof77 causes
KAP to be called with the -onetrip command switch.
Explicitly calling the compiler switch -noi4 causes
KAP to be called with the command switches -integer=2
and -logical=2 ; otherwise, the defaults are
-integer=4 and -logical=4 .
