It will be hard for us if you don't provide any info of your hardware connection, crystal speed and the PIC you're using.

Let's assume you use the same connection in the PBP manual.

Usually 4X20 LCD don't have 2 enable line. BUT some will need to place the 4 unused data bit to ground

Try with this snippet and let us know.

Code:
DEFINE OSC 4 ' Using 4 MHZ crystal
DEFINE LCD_LINES 4 ' Using a 4 lines LCD

pause 1000 ' wait LCD start-up delay 
           ' 
           ' P.S.: it can be higher or lower depending of
           '       the model you're using
           
Start:
      lcdout $fe,  1,"Line 1",_
             $fe,$c0,"Line 2",_
             $fe,$94,"Line 3",_
             $fe,$d4,"Line 4"
