ERROR Compling 16F819...l but the 16F818 works fine

[4Lewis]

I get an error when I compile for the 16F819... the same code works for the 16F818. Explaination?
---------------------------------------
DEFINE OSC 4
DEFINE ADC_BITS 10 'Set number of bits in result
DEFINE ADC_CLOCK 3 'Set clock source (3=rc)
DEFINE ADC_SAMPLEUS 50 'Set sampling time in us


TRISA = %11111111 'Set A to inputs
TRISB = %00000000 'Set I/O to output
ADCON1 = %10000010 'Port A Analog and right justify results


X VAR BYTE

LOOP:
ADCIN PORTA.1, X
Pause 50
If X > 100 Then
GOTO BLINK
ENDIF
GOTO LOOP

BLINK:
HIGH PORTB.4
Pause 100
LOW PORTB.4
RETURN

---------------------------------
Here's the error msg:
Error [124] C:\PROGRA~1\PICBAS~1.16\PBPPIC14.LIB [Illegal Argument]

Compiles fine for me on the 818 and the 819 (I use MPASM).

However, your troubles could be due to the “Return” at the end of the Blink section. Did you intend to use “Gosub Blink” instead of “Goto Blink” in the Loop Section?

Your suggestion of using "goto" did not work.

If you add -v to your command line when compiling, it should highlight the offending line during the compilation process to give you a clue where to look.

As Paul said you should be using GOSUB BLINK because you are calling a subroutine, and not GOTO BLINK as in your original post, which makes me suspect that the code you posted on the forum is not exactly the same as the code you have in your working program, because you will get a Stack Underflow the instant your try to run it on a PIC.

------ I should have stated I am using the complier that comes with PidBasic Pro called MicroStudio, so I don't know how to do the command line option you suggested. Thank you though ----

I have tried both "goto and gosub" with same result... I'll try again this morning and see what I can get! (fingers crossed)

It's probably a setting in your Microcode Studio (which I don't use). The reason I say that is that the only difference between a 16F818 and 819 is the memory. PICBasic will not give you a clean compile on the 818 and then an error on the 819. Sometimes I think IDE's give you more problems than they're worth.
