Primitive Definition.
Primitives are inserted into the frame payload. Primitive definitions are inherited by
descended frame templates.

Assigning '*' clears all previous settings (maybe from parent frame template).

Offset specifies the DWORD offset where this primitive is inserted in the Frame.

Count specifies how many times to repeat the primitive.
Examples:
Primitive : *
Primitive : SOF, 48 # where 48 = offset
Primitive : "CLOSE (NORMAL)", 36, 5 # where 5 = repeat
Prolog and Epilog define Primitive chains to be used at the beginning and end of the
frame.
Examples:
Prolog = SOF # For this frame primitive 'SOF' is a Prolog.
Epilog = EOF # For this frame primitive 'EOF' is an Epilog.
Frames can be derived from other Frames, therefore inheriting the layout of the parent
Frame. In this case, the user may:

Change Prolog and Epilog.

Change default field values.

Add new fields.
