Some language elements and features of ABL do not apply to all software platforms—operating systems, user interfaces, and database management systems—that OpenEdge supports. The documentation tries to note each such platform restriction with the language element title. Some language elements apply to SpeedScript programming and some do not; the documentation indicates which language elements do not apply with a note in the language element description. You can consider a language element as supported for all interfaces, on all operating systems, and for SpeedScript unless otherwise indicated in the language element description. The platform restriction notes that appear in the documentation include the following:
The element or feature applies only to the OpenEdge AppServer.
