4X20 TRULY LCD PPB lines 3 & 4

Hey there PIC masters of the Universe,
I have been programming in PicProBasic for a few years now and have never messed with LCD's in my projects until now. OK so dumb question...., but how do I write to lines 3 and 4 of my 4x20 display? I would also like to learn how to make use of my nifty graffic character positions. Any help would be very appreciated. My simple-sample code is below.

INCLUDE "modedefs.bas"
DEFINE OSC 12
CMCON = 7
TRISB=255
switch1 VAR PORTB.1
switch2 VAR PORTB.2

Pause 1000
loop:
Pause 19



LCDOut 254,1
LCDOut "I TYSON BOY GENIOUS"
LCDOut 254,257'........... 257 IS NOT A VALID CURSOR POSITION HERE
LCDOut "BOW DOWN TO ME"
Pause 11

IF switch1 = 0 Then message1
IF switch2 = 0 Then message2
GoTo loop

message1:
LCDOut 254,1
Pause 50
LCDOut 254, 130
LCDOut "HEY THERE USER!!!"
Pause 1000

GoTo loop

message2:
LCDOut 254,1
Pause 50
LCDOut "WHY DON'T YOU"
LCDOut 254, 197
LCDOut "TRY AGAIN?"
Pause 1000

GoTo loop

End

Standard parallel input 4x20 LCD?
See section 5.39 of the PBP manual, page 94.

thanks for the code and generator, i am still working on the graphics. Does anyone know about additional manuals for PPB on LCD's?

Nope, just this forum and experience..
