VMS Help RTL Routines, LIB$, LIB$PUT_OUTPUT  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    The Put Line to SYS$OUTPUT routine writes a record to the current
    controlling output device, specified by SYS$OUTPUT using the
    OpenVMS RMS $PUT service.

    Format

      LIB$PUT_OUTPUT  message-string

1 - Returns

    OpenVMS usage:cond_value
    type:         longword (unsigned)
    access:       write only
    mechanism:    by value

2 - Argument

 message-string

    OpenVMS usage:char_string
    type:         character string
    access:       read only
    mechanism:    by descriptor

    Message string written to the current controlling output device
    by LIB$PUT_OUTPUT. The message-string argument is the address
    of a descriptor pointing to this message string. RMS handles all
    formatting, so the message does not need to include such ASCII
    formatting instructions as carriage return (CR).
