! Declare $FAO_PUT macro for BLISS-36

MACRO  $FAO_PUT (indent, faostring) [] = 

    ! This MACRO is intended to provide an easier interface to the $FAO
    ! system service.  Using this, a control string, and the FAO arguments
    ! to that string are given.  If the FAO service completes successfully,
    ! the formatted ASCII text is printed on SYS$OUTPUT.  If not, the error
    ! status from $FAO is returned, and no text is printed.   The indent
    ! parameter will be used to determine how many <tabs> to place in front
    ! of the FAO control string.  This will be from one to n "!_" prefixing
    ! the string argument given.  (Note that indent is treated as a value
    ! and not an address)
