DEFINE /LIKE

        [SIC\]DEFINE Type Var1 [Var2 [...]] /LIKE VarLike

        DEFINE IMAGE Var1 File1 Key1 [...]] /LIKE VarLike

    The /LIKE option allows definition of  Type  REAL,  LOGICAL,  DOUBLE  or
    INTEGER  arrays  with  dimensions  identical  to those of the (existing)
    VarLike array. IMAGEs and TABLEs can also be defined in  this  way.  The
    dimension field must not be specified in such a case.

    The /LIKE option is incompatible with the  DEFINE  FUNCTION  and  DEFINE
    HEADER commands.
