Raw
Raw parameters, sometimes referred to as
unformatted, consist of a sequence of bytes that do not adhere any particular
data representation standard. Typically a variable of type X is used to pass
such raw parameters, although in the case of overlays, the data type specified
by the caller may not necessarily be X; it may also
be a MAP1 variable with MAP2 variables beneath it. Because
there is no prearranged standard to identify the end of the data, the length
must specified, either explicitly (in the routine documentation and/or external
parameter), or implicitly (by the size of the variable containing the raw
parameter).
