[A83] Error in SDK Documentation?



I was wondering if all the information in the SDK is completely
accurate.I've used VPutMap in loops to print out a null terminated
string, or something similar. I never preserve HL, yet this loop seems
to work fine. In the SDK, it says that VPutMap destroys "All but
BC".Here's an example loop.
 
 
ld hl,Text
call VPutFF
ret
 
 
VPutFF:
            ld a,(hl)
            inc hl
            cp 0ffh
            ret z
            B_CALL VPutMap
            jr VPutFF
 
 
Text: db "Example Code",0ffh
