Doing a SetLength on an array passed into a proc by reference
- by csharpdefector
Hi All,
Sure, even I can do this...
var
testarray : array of string;
setlength(testarray, 5);
but if I want to get clever and have a procedure into which I pass the array by referance like this I cant do it!
procedure DoStuffWithArray(var passedarray : array of string);
begin
setlength(passedarray, 5);
end;
compiler says 'incompatible types' on the single line of code in my proc.
I can do other stuff on the array like set set element values if i do a setlength before i call the proc, but I cannot do the setlength in my proc, which is what I want to do.
Any help much appreciated, thanks all.
