Syntax:  COMPILE compile_command

  Lets you compile the contents of a buffer without leaving LSE.

  When you enter this command, LSE writes the current buffer.  It then
  forms a command line by appending the file specification of the
  current buffer to the command string given on the COMPILE command.
  The default compile command is determined by the language
  definitions.  If no compile command is specified, then the compile
  command associated with the current buffer's language is used.

  If you want to generate a diagnostics file for use with the REVIEW
  command and the current language has diagnostics capability, specify
  the appropriate diagnostics switch in either the language's default
  compile command or in your (user-supplied) command.
