QL200 owners

Hello everyone,
I have a question about lcd defines. Here is my code:

DEFINE LCD_DREG PORTD
DEFINE LCD_DBIT 4
DEFINE LCD_EREG PORTA
DEFINE LCD_EBIT 3

Now this allows me to use the lcd on my QL200 developement board (ebay). One problem is that I must jumper wire the RS to RA4 for operation. Is there any way of getting around this?
I have tried adding:

DEFINE LCD_RSREG PORTA
DEFINE LCD_RSBIT 2

Which is where the QL200 is hardwired to, but still no good. There apparently are conflicts.
Any ideas anyone?

Just worked out how it needs to be done.

For 16F877A, need to add this code on top:

ADCON1=%00000111
DEFINE LCD_DREG PORTD
DEFINE LCD_DBIT 4
DEFINE LCD_RSREG PORTA
DEFINE LCD_RSBIT 1
DEFINE LCD_EREG PORTA
DEFINE LCD_EBIT 3
DEFINE LCD_BITS 4
DEFINE LCD_LINES 2
LOW PORTA.2

Then just use LCDOUT and it will work.
