====== GetPad( ) ======

''variable = GetPad(length)''
| //variable// |Variable to store results |
| //length// |Length of data to receive |

Reads length bytes from the pad buffer allocated with Set Pad.


<code xbasic>
   Const Device = CB280
   Dim X As Integer
   Dim Y As Integer
   Set Pad 0,4,20        'Mode 0, Packet size 4 bytes, Buffer 20 bytes
   On Pad GoSub ABC      'Define ABC as interrupt service routine
   Do 'Run forever
   Loop

 ABC:
   X = GetPad(2)         'First 2 bytes is the x coordinate
   Y = GetPad(2)         'Second 2 bytes is y coordinate
   Debug Dec X, Cr       'Print x coordinate
   Debug Dec Y, Cr       'Print y coordinate
   Return
