4bit hex decoder w/LCD

[rangerdoc]

I'm trying to write code for some hardware I'm going to build. With two purposes:
1) I have a 4-bit hex rotary encoder that will be inputs to the lower 4 bits of portA. I want the LCD to display an ASCII of the HEX encoder value.
2) I also have 4 momentary switches. They will be the lower 4 bits of portB. I have 4 LEDs on portC. When I press a momentary switch on portB, I want the cooresponding LED on portC to light & latch. When any other button is pressed, I want the first LED to go low and the new LED to go high and latch. Basically, I want portC to output & latch any value of portB other than 0.
All MCU inputs are optically isolated from the hardware they are operating.

I'm really new at this & this is my first code other than simple LED out type programs. Here is what I have:

'program for integrated firing panel
'portA = hexadecimal rotary encoder input (value to be displayed as an ASCII on LCD)
'portB = 4bit bank select momentary switches input
'portC = 4bit output to bank LEDs
'message = LCD display of portA (hex switch) value

'initialize device
@ device pic16f737, INTRC_OSC_NOCLKOUT, MCLR_OFF
OSCCON =  $60			'4mhz internal oscillator

'initialize ports
TRISB = $10			'make all portB pins outputs except B.4
TRISC = 0			'Make portC outputs
PORTC = 0			'Make sure portC pins start low

'initialize variables
TxPin var PORTB.4 		'alias pin B.4 to "TxPin"
rotary_in var word		'create variable "rotary_in"
banks var word			'create variable "banks"
rotary_in = PORTA & $0f	        'isolate lower 4 bits of portA & write to "rotary_in"
banks = PORTB & $0f		'isolate lower 4 bits of portB & write to "banks"
LEDs var PORTC			'alias PORTC as "LEDs"		

'Initialize Display
	Pause 1000		        'pause 1 sec to let LCD initialize
	serout TxPin,4, [22]		'turn display on, no cursor
	serout TxPin,4, [17]		'turn backlight on
	serout TxPin,4, ["Firing Panel  v1"]
	serout TxPin,4, [148]	        'move to line 2
	serout TxPin,4, [2]		'display custom character 3
	pause 5000			
	serout TxPin,4, [22]		'clear the screen
	pause 2000

message:
	serout TxPin,4, [22]	        'Clear LCD
	serout TxPin,4, [128]	        'move cursor to beginning of first line
	serout TxPin,4, ["Panel Selected:"]
	serout TxPin,4, [199]	        'cursor to middle of second line
	serout TxPin,4, [#rotary_in]	'display ASCII of portA lower 4 bits on LCD
	END

leds:
	If banks > 0 Then		'for all port B.0 thru B.3 values, except 0,
		banks = PORTC 	        'write value of portB to portC
	Endif

goto message			        'loop LCD forever

End

The whole thing compiles fine except for Error Line 44: Syntax Error. Is this line 44 of the PBP or the ASM code? Does that include blank lines and comments as a line? In other words: which is line 44?
Any help would be appreciated. I know most of you could find much better ways of writing this, but I need to keep it simple, even if it isn't the most efficient way of doing this. That way I can continue to work with it and learn from it in the future. The inputs and outputs will be so slow that speed isn't an issue.
One thing I don't like is that in the "leds:" routine, I'm writing a binary value to the whole portC when portC.4 is TxPin. Not sure if this will create problems.
Attached is the assembly file created by PBP.

Thanks
