The system looked for the named variable in the current procedure, then in the procedure that invoked the current procedure etc., and finally it looked for a global variable of the same name. Using NEW <word> you could create more than one local variable with the same name in the same procedure e.g. REPEAT 5 [NEW 'X] but that was a bit pointless because all but the most recent instance were inaccessible and null. > > I have no idea whether anyone still has Nimbus Logo or Terak Logo any more. They were extant in 1984. If anyone still has a working copy of either, please tell me: I'd be most interested. > > Ken Johnson I'd be extremely interested as well.
