Reserved words

Below is a list of all the reserved keywords in the VPL language. Some of the words are not documented but are reserved either because they are used internally or because they will be included in the VPL syntax at some later time. Please also note that there is a number of standard functions,  function blocks and platform support functions that are normally included in a VPL program (when using the INCLUDE statement).
