Pointers to arrays with dual indexes

[Bern Ertl]

Just fixed a bug in my code. The PB/DLL 6.0 manual (didn't
check the help file) contains an error in the sample code on
pages 53 & 54.

The description correctly states that 'limit' in the "OF limit"
clause is zero based, but the sample codes shows as if it was
BASE 1.

#COMPILE EXE

FUNCTION PBMAIN AS LONG
   
   LOCAL ptrGraph AS LONG PTR
   LOCAL x&, y&
   
   x&=8
   y&=3
   
   DIM Graph&( x&, y&)

'   INCR x&  'Per PB manual
'   INCR y&  'Per PB manual
   
   ptrGraph = VARPTR( Graph&( 0,0) )
   
   @ptrGraph[ 3 OF x&, 2 OF y&] = 4
   
   MSGBOX "Graph(3,2)="+STR$( Graph&(3,2))
   
END FUNCTION

Hmmm.. well spotted. Thanks!
