[Delphi] Variables in statement

[iLuvCoding92]

How to I create a variable in the statement(between the begin and end;) instead of before the statement? I don't want to waste a lot unused array. I want the program to be able to change the no. of array during runtime.

Ok, then use dynamic arrays.

procedure YourProcedure;
var
  MyDynamicArray : array of Integer;begin
  SetLength(MyDynamicArray,100); // This allocates dynamically memory for your array
  ....
  // some operations with the array
  ....
  ....
  SetLength(MyDynamicArray,0);
  // Now you haven't any allocated memory for the array
  ....
  ....
end;

Best regards
