Description

Removes a substring from a string, or removes elements from a dynamic array and returns the modified array.

In Delphi code, Delete removes a substring of Count characters from string or array S, starting with S[Index]. S is a string-type variable. Index and Count are integer-type expressions.

If Index is larger than the length of the string or array (or less than 1), no characters are deleted.

If Count specifies more characters or array fields than remain starting at Index, Delete removes the rest of the string or array. If Count is less than or equal to 0, no characters are deleted.

Note: Delete uses one-based array indexing even in platforms where the strings are zero-based.

Dynamic Array Example

  
var
  A: array of integer;
begin
  ...
  A:=[1,2,3,4];
  Delete(A,1,2); //A will become [1,4]
  ...
end;
