        [SIC\]MESSAGE Severity ProcedureName "Message"
        [SIC\]MESSAGE  Severity  ProcedureName  Arg1  Arg2 ... ArgN [/FORMAT
    Fmt1 Fmt2 ... FmtN]

    Print a message using the same mechanism as the one used by Gildas  pro-
    grams.  In particular, it will be printed or not, to the terminal and/or
    to the message file, depending on the filters that  currently  apply  to
    messages.
    - The  severity  must  be  a  single  letter  from one of the following:
      F)atal, E)rror, W)arning, R)esult, I)nfo,  D)ebug,  T)race,  C)ommand,
      U)nknown.
    - The procedure name is a free character string.
    - The message must have at least one component. Multiple remaining argu-
      ments will be printed out spaced by a single space. Enclose with  dou-
      ble-quote a character string if you want to use more than one space.
    - If /FORMAT option is invoked, each argument is displayed using its as-
      sociated format. Formats are Fortran ones (so may be slightly machine-
      dependent) like a10, i2, f5.2 and so on.

    Example:
    SIC> MESSAGE I FOO "Hello world!"
    I-FOO,  Hello world!

    SAGE command.
