Distinction of HOST code and PC code

Px, p, Hx, h, <, and > are a DBCS-PC, SBCS-PC, DBCS-HOST, SBCS-HOST, SO (Shift Out), and SI (Shift In) character, respectively. The following is an example of the use of such notations.

PC                                    HOST
                    Upload
'pP1P2p'   ------------------------ 'h<H1H2>h'

Code Conversion
SO/SI insertion

p     : SBCS-PC
P1,P2 : DBCS-PC
h     : SBCS-HOST equivalent with p
H1,H2 : DBCS-HOST equivalent with P1,P2
<,>   : SO,SI
