Need some help with BS2 syntax - IF...THEN

Otaku1031

Hi all,
I'm having some difficulty with getting this sequence to work:
I'm using pin 12 as an input for a logic signal from a CD4070 gate. I need to look at this signal, determine if it's 0 or 1, and take the appropriate action. If the signal is 1 (indicating a test failure) I want to make pin 13 high to turn on an LED. Here's what the code looks like right now:

IF IN12 = 1 THEN OUT13 = 1
END IF

When I check syntax, I keep getting errror msg's like "Expected: Label". I've been using Excel VBA for > 10 years, but this is my first exposure to PBASIC. I can't seem to find a code example anywhere that shows how to turn a pin ON based on the input (high/low) to a different pin. I have pin 12 defined as an input and 13 defined as an output. Can anyone point me in the right direction? Many thanks!

When your IF Statement is completed in one line you do not need the ENDIF.

Also, ENDIF is one word.

Thanks, Rich. I was able to get the Syntax Check to accept this:

IF IN12 = 1 THEN Fail_LED
END

Fail_LED:
HIGH 13
END

I may stick with this, as I'll need to reference Fail_LED several times in this program. I'll test your suggestion first thing when I get back to work. Thanks again!

"END" belongs only at the end of the program. You do not need to "end" the IF statement if it takes only one line.

This needs an ENDIF;

IF a = 1 THEN
b = a + 1
GOSUB somethingElse
PAUSE 10
ENDIF

This does not need an ENDIF;

IF a = 1 THEN GOSUB somethingElse

Aha! Hey, thanks again. This will make things go faster.

If in12=1 then high 13

Or simply, assuming p13 has already been made an output,

out13 = in12

@Tracy: Molto elegante!

Yessir, that "END" command stops everything..... as in, the micro does absolutely nothing else unless you cycle power (reset) and force a program restart. So in the example you give, the program will perform the check and in either case (True/false) it stops execution. This may be exactly what you intended, but I imagine you'll need some kind of a branch function too, GOSUB or GOTO
