Hi,
I have a mildly recursive function, and it isn't doing what I expect.

id as integer

TestId()

function TestId()
id = id + 1
message str$(id) ` display current value of id
TestId()
endfunction

id always equals 1 but I would expect it to increment.

Why is this?

Thanks

Doh! I was missing the global scope specifier. Works as it should now.

it is because you don't pass it through the function so its local to that call. You would have to either global it or make it a parameter and put it through the function.
