Programming Error HELP needed..!!

[namees22]

hi guys,

as a part of my pic programming i used to address a port pin as LATA.F0(found it from Engineers garage),but my Compiler throws an error for this..so i replaced with LATA0.and it got compiled well but that port isn't responding to my program.am using PIC C18 compiler Lite version.for my PIC18F4550..somebody please help me.

could you please explain which port pin you want to address, is it an ADC pin or other??

port b for lcd data pins,lcd control pins to port a(1,2,3)...i need to know how exactly port should be addressed..i have used 8052,PIC16F877A...is LATA.F0,LATA.F1,LATA.F2..wrong or LATA0,LATA1,LATA2 ..am not getting output for both...instead am usng oscillator circuit(4 leg) rather than crystal(2 leg)..can u help me out..in it..

Hai,
Did you set the direction register (TRIS register)?
Try this also,

LATAbits.LATA0

# define PORTBIT(adr,bit)         ((unsigned)(&adr)*8+(bit))

static bit	YBzc    			@	PORTBIT(PORTB, 7);       // pin 40 of IC
static bit	rs  				@	PORTBIT(PORTC, 2);      // pin 15 of IC
static bit	en1 				@	PORTBIT(PORTC, 3);      // pin 16 of IC
static bit	en2 				@	PORTBIT(PORTB, 5);      // pin 38 of IC   
static bit	clk 				@	PORTBIT(PORTB, 1);      // pin 34 of IC
static bit	data 				@	PORTBIT(PORTB, 2);      // pin 35 of IC 
static bit	str 				@	PORTBIT(PORTB, 3);      // pin 36 of IC
static bit	oen 				@	PORTBIT(PORTC, 5);      // pin 24 of IC

Here is the sample of how to define port pins,I have done this for 18F4620 Hitech compiler for PIC 18
