[1] Oracle implements hints by using specially-crafted comments in the query that begin with a + symbol, thus not affecting SQL ...
That initial value may or may not be modified by the called program. Any changes made to the parameter are returned to the calling program by default by copying but - with the NO-COPY hint - may be passed by reference. PL/SQL also supports external procedures via the Oracle database's standard ext-proc process. [9]
HINT is intended to be "scalable" to run on any size computer, from small serial systems to highly parallel supercomputers. [1] The person using the HINT benchmark can use any floating-point or integer type. [2] HINT benchmark results have been published comparing a variety of parallel and uniprocessor systems. [3]
