Storing global references between Spin objects

Randyy

Hello all,

I've been beating my head against the wall for a week now with a problem. Searched forums, but I can't find a solution. Hopefully someone can help.

Simplifying my problem, I have two objects, the main object and a support object with several public methods. I can pass a reference to the .start method in the support object and successfully refer to it via Long[reference], both writing and reading from WITHIN the method. I can't seem to save that reference however for use from other methods in the object. I've tried

myGlobal := reference 
    and 
myGlobal := Long[reference]

, both with and without the @ sign, and my other methods don't seem to be able to read or write to the main object's variable. Can anybody tell me what I'm doing wrong?

In the parent object you have this:

VAR
  LONG reference ' could be a local variable too, if you aren't starting a second cog using the variable

PUB Main
  SUB.start(@reference)

In the child object you have this:

VAR
  LONG refAddr

PUB start (ref) ' pass the address to the variable as the parameter
  refAddr := ref ' store address to global variable
  dothings(ref) ' or pass it to methods...

PUB dostuff
  LONG[refAddr] := 5
  display(LONG[refAddr])

PUB dothings (ref)
  display(LONG[ref])
  LONG[ref] := 12

hope that helps.

Thank you in advance (away from my Prop right now). It seems like I was doing this, but maybe not quite. In your example, I could get .start and .dothings working, but .dostuff was the problem. I'll try it tonight and report back.

It worked! Thank you!
