Re: Debugging very (very) complex data structures

Hi David,

I had similar problems lately when debugging - I defined a based field and data structure and set the pointer to the pointer to the right address - so I could look at the correct part at my breakpoint.

I also tried the "System Debugger" that is supplied by iACS - but I found other problems with that one. I haven't tried the Code4i debugger - maybe this one will give better results.

Have you already tried it with STRDBG? As cumbersome and humble as it is, sometimes it's my last resort, if everything else fails me.

I would be happy to hear, if you found another solution.

HTH and kind regards,
Daniel

Folks:

Does anyone have any advice for debugging programs that have very
complex data structures?

I've got a number of programs that have multiple nested data structure
arrays and cannot get the debugger to show me their values.

I either get a ...

dbge0004E could not evaluate expression xxx

... or ...

CRRDG3137E The given expression could not be monitored.
Server: CPF8E32 Debug Interpreter Heap limit reached.

... error messages.

I've tried qualifying the data structure that I want to monitor as
much as possible... Using the variable the program is using to
reference the structure array element ...
structure(x).substructure(y).subsubstructure(z)

I've also tried specifying the array index values explicitly ...
structure(1).substructure(2).subsubstructure(3)

Neither works.

Regarding the CPF8E32 error above ... is there a way to increase the
debug interpreter heap limit?

Thanks!

david
