Could anyone explain this screen:

enter image description here

As you can see I have simple array - debugger shows values of its elements when I use A[0], A1... but I cannot get elements with local variable A[i] (but value of "i" is shown correctly).

Project settings:
Debug info: ON
Local Symbols: ON
Optimization: OFF.

Project (one PAS file) is BUILD so DCU is fresh. You can see on that screen almost full code of this test project so there is no chance that array A or "i" is declared in some other unit etc...

Now I checked - the same code in Delphi XE3 works perfectly - debugger shows all values. It seems that XE4 has a serious bug in basic feature :-((

    check properties for A[i] watch and try to setting "allow function call" there. Just shooting into the skies. – Arioch 'The May 29 '13 at 06:36

    try adding `j:integer` variable, adding `j := i` into the loop body and watching `A[j]` instead. It is exotic tome (XE2 user) to see i grayed out and i cannot see any other reason, than it being loop-variable. BTW, turning optimizations ON, would it help ? – Arioch 'The May 29 '13 at 06:38

    Please post your "Project Options" window selecting the "Compiler" item so that we could see the full configuration. – gustavogbc Jun 05 '13 at 22:33
  • What does `High(A)` return? I'm not sure how `High` works with associative arrays, but is it possible `High(A)` is returning the highest value, not highest key? If that's the case, it may be trying to access `A[2]`, and that is inaccessable – dKen Jun 07 '13 at 11:51
  • I tried to reproduce in an older version of Delphi and had some likely behavior... ALthough, in my context, Optimization was ON. I would like to compare your full configuration (your "Project Options" window selecting the "Compiler") with mine, @rafal-chlopek. – gustavogbc Jun 07 '13 at 22:06
  • @dKen: `A` is not an "associative array". It is an ordinary static array. `High(A)` is `1`. – Andreas Rejbrand Dec 18 '19 at 13:07

It doesn't work because 'val' is a function and not a variable. Double click on the watched item and check the property 'allow function calls'.

    It's clearly visible from the code the OP posted, that 'val' is an integer child element (that is: variable indeed) of the record named 'TSome', and A is an array of that record. Therefore, A[i].val is pointing to an integer variable and not a function indeed... – That Marc Apr 29 '16 at 22:01

i is a var and this var need an amount for instance change i to 1 and check it;

A[1].val;
