How to initialize the array

[krzynio]

Unfortunately the same error: unit1.pas(12,37) Error: Incompatible types: got "Constant String" expected "WideChar"

and the below code is not working also:

Code: Pascal  [Select][+][-]

1. var
2. PLChars: array[0..17] of WideChar;
3. i: integer;
4. begin
5.   PLchars[0] := 'ą';  // doesn't work
6.   i := ord('ą'); // doesn't work,  unit1.pas(47,8) Error: Ordinal expression expected
7.

Make sure that your file has a UTF-8 BOM (in Lazarus right click the text editor, then File Settings -> Encoding -> UTF-8 with BOM and then select the Change File option in the dialog), then the compiler will handle this correctly. Alternatively you can add {$codepage utf8} at the top. Without either of this the compiler will see a such a character as a 2 Byte sequence which is longer than a single character which still is AnsiChar no matter what it's assigned to.

Hello, I am a beginner and I was trying to get a value from the string and put it into the array. An error message "Warning: Variable "code" of a managed type does not seem to be initialized". How do I solve it?

It's just a warning, in case you forgot to initialize the array (or other managed type, like String), and it can usually be either ignored or shut down by initializing it, for example with:

Code: Pascal  [Select][+][-]

1. code := Default(TStringArray);

Sorry for bringing up this old Thread, but ..

Simple solution (to avoid the compiler warning ..) would have been

Code: Pascal  [Select][+][-]

1. code := NIL;   // empty array
2.  

or

Code: Pascal  [Select][+][-]

1. var
2.   code:TStringArray = NIL;
3.  

Indeed Default does the same, but beginners probably won't find instructions for Default easily.

I myself also didn't know this by now. Still learning every day ..

Well, the wiki might be not clear, but the official documentation usually is :
https://www.freepascal.org/docs-html/rtl/system/default.html
Users should refer to the official documentation first, only then refer to the wiki.
