LOWERCASE Directive 

The LOWERCASE directive turns on or off shifting to lower case of all
FORTRAN external names.  This directive does not affect the external name
of the ALIAS and EXTERNAL_ALIAS directives or intrinsic names if
"$LITERAL_ALIAS ON" has been specified.

See "ALIAS Directive"  and "LITERAL_ALIAS Directive" .

Specifying $UPPERCASE ON (or $UPPERCASE) is equivalent to specifying
$LOWERCASE OFF.
Specifying $UPPERCASE OFF is equivalent to specifying $LOWERCASE ON (or
$LOWERCASE).

Syntax 

$LOWERCASE [ON ]
           [OFF]

Default               On; all FORTRAN external names are shifted to
                      lowercase.

Location              The LOWERCASE directive can appear anywhere within
                      the program unit.

Toggling/ Duration    Can be toggled with either another LOWERCASE
                      directive or with an EXTERNAL_ALIAS directive.
                      (Note that the EXTERNAL_ALIAS directive cannot be
                      used after the appearance of nondirective
                      statements in a program unit.)

                      If the LOWERCASE directive is toggled within a
                      program unit, the point of declaration (or the
                      point of first use if implicitly declared)
                      determines the case of external names.
