Library /sys$common/syshlp/sda.hlb SEARCH, /LENGTH=length_specifier  *Conan The Librarian (sorry for the slow response - running on an old VAX)

     This qualifier specifies the size of the expression value to be
     used for successful matching during searches of memory. The
     possible values of this qualifier are:

         LONGWORD - specifies that the expression to be searched for
                    is four bytes in length. This is the default value.

                    is two bytes in length.

         BYTE     - specifies that the expression to be searched for
                    is one byte in length.
