Unable to set breakpoint at break-addr, no write access. Your
 program cannot be debugged unless you can change the write access
 of your code.

    Facility: DEBUG, VMS Debugger

    Explanation: Most debugger startups set a breakpoint in the user
    program and then return control to that program. The debugger
    regains control when that breakpoint is hit. It is necessary for
    the debugger to have write access to the user program in order to
    set breakpoints.

    User Action: Change/allow write access to your program's code.
