GP2 on a 10F202 as output

[skimask]

I read the whole datasheet of the 10F202 and I did not succeed in finding how to set GP2 as an output.
When I put a led via a resistor at GP0, GP1 and GP2 only the GP0 and GP1 leds are working the led on GP2 remains off. (not broken).
See small example.
What do I forget ??

		'test voor 10f202
			
		@ DEVICE PIC10F202,INTRC_OSC
		@ DEVICE PIC10F202,MCLR_OFF
		@ DEVICE PIC10F202,PROTECT_OFF
		@ DEVICE PIC10F202,WDT_OFF
		
		DEFINE	OSC	4
				
		TRISIO	  = %00000000
		OSCCAL.0  = 0
		
		UIT1	VAR	GPIO.0 : UIT2	VAR	GPIO.1 : UIT3	VAR	GPIO.2 : IN1	VAR	GPIO.3
	
BEGIN:
		IF IN1 = 0 Then
		UIT1 = 0:UIT2 = 1:UIT3 = 0
		EndIF
		
		IF IN1 = 1 Then
		UIT1 = 1:UIT2 = 0:UIT3 = 1
		EndIF
		
		GoTo BEGIN

10F202 datasheet (DS41239A)....page 21 (Section 4.6) and page 37 (Section 8.0) will give you all the answers you need.

i'll bet on

OPTION_REG.5=0

@ Skimask:
I read that part. Thats why I put in the programm :OSCCAL.0 = 0

@ Mister_e:
You win the price. That helped.
I read also that the option reg bit 5 should be 0 , but I wrote at that time in my programm OPTION.5 = 0 , and the compile gave me an error. I forgot to type it in the correct way.
Thanks.

yup OPTION.5 won't work unless you decide to redefine it

@OPTION=OPTION_REG
OPTION VAR BYTE EXT
    ' or the simple one
OPTION VAR OPTION_REG

Doesn't help if you don't know OPTION_REG

In this case you could still open the filename.ASM file, there you'll have...

R0              		EQU	RAM_START + 000h
R1              		EQU	RAM_START + 002h
R2              		EQU	RAM_START + 004h
FLAGS           		EQU	RAM_START + 006h
R4              		EQU	RAM_START + 007h
R3              		EQU	RAM_START + 008h
GOP             		EQU	RAM_START + 00Ah
OPTION_REG      		EQU	RAM_START + 00Bh
RM1             		EQU	RAM_START + 00Ch
RR1             		EQU	RAM_START + 00Dh
SOFT_STACK_PTR  		EQU	RAM_START + 00Eh
TRISIO          		EQU	RAM_START + 00Fh
SOFT_STACK      		EQU	RAM_START + 010h

I know, but still !!

I can not seem to program a 10f202 I always get "programming error at 0000" however if I read it I can write the info back to the chip?

Code?
What are you reading from the chip ?
