asm e picbasic

Hi all,
I have a problem. After compiling, PicBasicPro generates a warning error:

Error[118]C:\test.asm53: Overwriting previous address contents (000E)
Error[118]C:\test.asm54: Overwriting previous address contents (000F)
Error[118]C:\test.asm55: Overwriting previous address contents (0010)
Error[118]C:\test.asm56: Overwriting previous address contents (0011)
Error[118]C:\test.asm57: Overwriting previous address contents (0012)
Error[118]C:\test.asm58: Overwriting previous address contents (0013)

and so on.. It does not work. Why?

this is code:
---------------------------------
DEFINE OSC 4

define LCD_DREG PORTB
DEFINE LCD_DBIT 4
DEFINE LCD_RSREG PORTB
DEFINE LCD_RSBIT 3
DEFINE LCD_EREG PORTB
DEFINE LCD_EBIT 2

ASM
BSF STATUS,5
movlw 00000b
MOVWF TRISA
BCF STATUS,5
LED BSF PORTA,0
END
ENDASM

lighting:

LCDOUT $fe,1,"light!"

I get...

[235] Opcode Expected Instead of 'LED'

...which is pretty understandable since your posted code isn't complete!

Fisrtly your code isn't going to work... you got serious logical errors (the code is a bit of a mish-mash... have you simply cut & paste or do you have a plan and know what you're doing?)... but that aside...

If you're going to mix Assembler and PICBasic you can't specify a low-order ORIGIN (your ORG statement), because PICBasic will start assembling it's code down there. If you really need to specify a fixed location for your code, dump it in high memory space, well away from where PICBasic will place it's code.
