LONG Directive 

The LONG directive sets the default size for integer and logical data
types and constants to four bytes.  The INTEGER and LOGICAL type names
are set equivalent to INTEGER*4 and LOGICAL*4, respectively.

Syntax 

$LONG [INTEGERS]

INTEGERS              Optional; this word has no effect.

Default               LONG (4 bytes) if neither the LONG nor the SHORT
                      directive is given.

Location              The LONG directive must appear before any
                      nondirective statements in the program unit,
                      including the program head.

Toggling/ Duration    Cannot be changed after the appearance of
                      nondirective statements in a program unit.
