1836.0. "How to Debug DCL.EXE ?" by COMEUP::SIMMONDS (loose canon) Sun Apr 27 1997 05:08

    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....
1836.2	One doesn't need the linker...	XDELTA::HOFFMAN	Steve, OpenVMS Engineering	`Mon Apr 28 1997 12:42`	2
	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.

(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.
