Case String of Error
« on: November 27, 2020, 09:38:14 am »
Hello,


Pls Help i don't understand:

Code: Pascal  [Select][+][-]
  1. Case Trim(SamBesch) Of
  2.  
  3.       ('1/2 '+Afz+Afz),('½'+Afz+Afz) : Begin
  4.           If EinAus = 0 then Begin      //Ein
  5.              BsamEin.Caption := (12.7).toString;
  6.           End Else Begin
  7.              BSamAus.Caption := (12.7).toString;
  8.           End;
  9.       End;

This is simply a case statement with string selectors of the form:
Code: Pascal  [Select][+][-]
  1. case Trim(SamBesch) of
  2.   string1, string2:
  3.      begin
  4.         some code...
  5.      end;
  6. end;

And explain a little more what "doesn't work" means: what does it do that it shouldn't?, what doesn't do that it should?, what are the inputs?, etc.

Its Just A Case String of
   ...
 ...

But i Get The Error that "('1/2 '+Afz+Afz)" isn't a String
 i use Afz Because the " ' " Char is used for Strings so i wasn't Sure if i could have just done this : ('1/2 ''''')
im Just building this String and then use it in case Statement

Whenever you need a quote inside a string constant,
'You''ve just to double it',
so yeah, '1/2 ''''' would store: 1/2 '' in the string.
