Ord Funcition

[Henry Olive 5]

Good Day

 

I'm trying to get a char's alphabetic order number

for example  A=1,  C=3... etc.

 

Edit2.Text := IntToStr(Ord(Edit1.Text));

with above code I'm getting  37331868 for A (expecting 1)

what am i doing wrong ?

 

Thank You

Edit1.Text is a string, which internally is a pointer. So Ord returns the value of the pointer.

 

Better identify the char you are interested in: Ord(Edit1.Text[1]);

Thank you so much Uwe, your code works but the result is not as my expectation

 

//Edit1.Text = A

Edit2.Text := IntToStr(Ord(Edit1.Text[1]));    Result = 65,  Expecting 1

 

//Edit1.Text = B

Edit2.Text := IntToStr(Ord(Edit1.Text[1]));    Result = 66,  Expecting 2

If you have capital Latin letters then just subtract 64.

In case of small Latin letters then subtract 96.

Ord returns the ordinal value of the character, not its position in the alphabet.
