Hello,

In the screenshot, notice the array "Output" is there twice.  Once
showing every character individually quoted and a second time as a
string (with only two quotes.)

The question is: is it possible to have the format as shown in the
second instance (@Output[0]) but without having to create a second
instance ? 

Thank you for your help.

As long as there is a PChar cast involved, no. You know that as
opposed to PChars, Pascal strings can contain zero's at any spot.
Looks to me only the first one is correct, but it is possible to see
the content of the hex pointers in hex for the second one and since
you can read hex, use that.

there is a setting on the setup of the display-formatter, that allows
to show or hide the original value

Sorry, partly misread the question.

But still, if you use the displayformatter for "array of char as
string" then you can have both outputs => on the same line though,
which means one may need scrolling.


If you don't mark the display formatter as checked (in the list /
config), then you can select it for individual watches, in the watch
properties.

Hi Martin,

First, I'm using Lazarus v3.4 (64 bit)

I am unable to find the option for "displayformatter for "array of
char as string".  I've tried the field's properties in the watch
window and the Tools->Options->Debugger but, I don't see an option
like that.  Can you provide more specific information please ?

Same question, I can't find a place to "mark the display formatter as
checked".  Where do I find that option ?

Thank you for your help.
