I am looking for a way to access variables between the upper program and the variables set out in the objects in that program.· I would like to have a number of variables defined in the top level of the program and then have an object access that data and to have the object write data to some of the variables defined in the upper program. Is there a way of accessing that or will I have to copy the information to and from·that object's variable area.· Any help you can provide is appreciated
Thanks: Mike

Use pointers.

Just pass the variable addresses to the lower level objects.

The use word[address] or byte[address] or long[address] to set or read the variable.



byte stuff1
word stuff2
long stuff3

PUB writeStuff

byte[@stuff1] := 128

word[@stuff2] := 32768

long[@stuff3] := 1231231231

PUB readStuff1

return byte[@stuff1]

PUB readStuff2

return word[@stuff2]

PUB readStuff3

return long[@stuff3]
