Luke,
a dynamic array is an array of pointers. There are two things
I think you can do:
1.
var MyArray: array of TSomething;
MyBuffer: array of TSomething;
setlength(MyArray, 50);
{do stuff with MyArray}
setlength(MyBuffer,49);
MyBuffer := (copy(MyArray,0,19)+copy(MyBuffer,21,49));
{as a way of deleting element # 20}
{should work}
2. You might try
MyArray[20] := Nil;
this would dereference that element - but I am not sure how the
rest of the array would behave after that, should you try to
iterate through it afterwards .... try it out ;-)
You can always simply truncate a dynamic array using the
Setlength function - all data past the truncation point simply
gets discarded and I know this to behave in a benign fashion
as it is something I have used in the past.
H.t.h. - should give you something to play with anyhow ;-) -Peter
