ShortString
│ English (en) │
Memory requirement: 256 bytes (1 byte for the length specification and 255 bytes for the characters).
Property: The data field of the data type Shortstring is an array, made up of data fields of the data type Char. Its length is defined as: ShortString = String[255];
ShortString has the same properties as the string in Turbo Pascal.
Definition of a data field of the data type ShortString:
var
s : ShortString;
Examples for the valid assignment values:
s := '0123ABCabc456';
s := s + '! "§ $% & / () =?';
s := 'c';
s := s + IntToStr (45);
Examples of invalid assignment of values:
s := True;
s := 4;
Caveats
Warning: low(myShortString)
returns 0
, i. e. the index of the length Byte, not the first character’s index. Likewise, high(myShortString)
always returns 255
. Use length
instead.
Nevertheless, a for … in
loop will work as expected.
