Public will create the variable, like Local, assigning .f. as default value. Another difference is that Public will survive any level, for example (sorry, just saw you said topLevel)

test2()
test3()

? somePubVar && somePubVar exists, defined in test1
? somePrivVar && somePrivVar does not exists

procedure test1()
? somePrivVar && Valid, defined in test1
? otherPrivVar && invalid, private does not define the variable
return

procedure test2()
public somePubVar
private somePrivVar, otherPrivVar
somePrivVar=0
test1()
return


procedure test3()
? somePubVar  && valid defined in test2 as public, value is .f.
? somePrivVar && Error, somePriv went out of scope already
return
