1836.0. "How to Debug DCL.EXE ?" by COMEUP::SIMMONDS (loose canon) Sun Apr 27 1997 08:08

    In attempting to find what's at the root of the DCL problem
    posted in VMSNOTES 489.0, I'm wondering how OpenVMS Engineers
    manage to run DCL.EXE under a debugger.. Would some kind person
    care to share a hint or two, pleeeease? :)
    
    Thanks!
    John.

    It has to be linked /DEBUG=DELTA and with another module that 
    calls into DELTA when DCL starts....
1836.2One doesn't need the linker...XDELTA::HOFFMANSteve, OpenVMS EngineeringMon Apr 28 1997 15:422
   One can likely patch in the debugger bootstrap and the breakpoint.

    I don't think that will work.  DCL is not activated like a normal
    image... so I doubt you can get the debugger image activated. Which
    is why DELTA is linked into the image.

    Dave, 'I want one of those!!' .. Really! Could you mail me such a beast ?
    (for Alpha V7.1 or V6.2; doesn't matter which)  I know this is
    "cheating", but, at least I'll feel that my weekend spent (fruitlessly)
    desk-checking the source listings and peeking around with SDA wasn't
    totally miss-spent.. :):)  Of course I'll forward the bug details to
    you when I find it..
    
    Thanks!
    John.
