LIB$GET_SYMBOL

   The Get Value of CLI Symbol routine requests the calling
   process's command language interpreter (CLI) to return the value
   of a CLI symbol as a string. LIB$GET_SYMBOL then returns the
   string to the caller. Optionally, LIB$GET_SYMBOL can return the
   length of the returned value and the table in which the symbol
   was found.

   Format
