Primitive 07, used with the Program Upload and Download Primitives (58
and 59), obtains the attached device segment definition as an ASCII string.
The definitions contain the segment number they represent and relate
one-to-one with the MMMM descriptor (starting at bit P) defined in
Primitive 58. Primarily, this request determines a starting point from which
to obtain the definitions. This allows you to obtain ASCII strings that would
otherwise exceed the maximum returnable length.
