/READ_ONLY (D)
       /NOREAD_ONLY

    Specifies whether or not the indicated buffer should have the
    read-only attribute. If the buffer has this attribute, then LSE
    does not write the contents to a file when you exit from LSE or
    when you issue a COMPILE command. This qualifier has an effect
    only if the GOTO BUFFER command is creating a buffer. If you are
    going to an already existing buffer, the read-write status of that
    buffer is not changed. The /WRITE qualifier is equivalent to the
    /NOREAD_ONLY qualifier.
