LET /NEW

        [SIC\]LET Variable [=] Expression /NEW Type [Attr]

    Define  the variable and assign it at the same time. Type is the type of
    the variable (INTEGER, REAL, DOUBLE,  LOGICAL,  or  CHARACTER).  INTEGER
    stands  for  SHORT  or LONG integer depending on the current SIC INTEGER
    rule.

    The optional Attr argument is used to specify whether the newly  created
    variable is LOCAL (default) or GLOBAL. See also the SIC\DEFINE command.
