Symbol issues?

[fritz42_male]

Hi guys,

Can someone explain what I'm doing wrong - I want to use sensible variable names and most of what I'm doing is working OK but just keep on getting a syntax error

#Picaxe 18M2
symbol PIR_IN=B.7
symbol PIR_COUNT=w0
		
Init:								'Staring point to setup all inputs, outputs and set variables
        debug 
	Pause 6000'0					'Wait 60 secs for PIR to 'settle down
  
 PIRtest:
	Do : Loop Until pinB.7=1
	Do
	PIR_COUNT = PIR_COUNT + 1 * pinB.7
	Loop Until PIR_COUNT = 10
	PIR_COUNT = 0

All I want to do is use PIR_IN instead of pinB.7 but it keeps telling me it's invalid syntax! e.g. D0: Loop Until PIR_IN=1

And if it looks identical to what Halstaff is doing that's because it is. We are collaborating on some Halloween stuff.

My first post from the iPhone app, so I hope this reply goes to the right place.

I think your issue is that "Do:" is not a valid label as it is a keyword. Try changing it to "DDo:" or something else.

The issue is that PIR_IN is replaced with B.7 (a reference to an output). If you change

symbol PIR_IN = pinB.7

it should work as expected.

@IronJungle,
The line you are discussing is a tight loop, that is DO : (nothing) : LOOP, not a label named DO:

@Fritz
Try the line as:
symbol PIR_IN=pinB.7

When I load the code in the Program Editor I do not get a syntax error. What version of PE are you running?
Does it support the 18m2 ? Remove the #Picaxe 18m2 directive and see what happens.

Thanks guys. PIR_IN=pinB.7 works fine. Just read through that section of the manual as well.

Well, you learn something everyday. Thanks,
