Merlin’s Delphi Forge

The string length is automatically set but sometimes you want to change the length yourself. That’s because sometimes you have to have the same length of a string every time (when saving to binary files). You can always use the string[n] (ShortString) type but their maximum length is 256 characters.

!!Note: You CAN NOT set the length of string constants.

var
  sString: string;
...
  { This code sets the string length to 512 characters }
  SetLength(sString, 512);
