Delphi Compiler Error
E2246 Need to specify at least one dimension for SetLength of dynamic array
Reason for the Error & Solution
The standard procedure SetLength has been called to alter the length of a dynamic array, but no array dimensions have been specified.
program Produce; var arr : array of integer; begin SetLength(arr); end.
The SetLength in the above example causes an error since no array dimensions have been specified.
program solve; var arr : array of integer; begin SetLength(arr, 151); end.
To remove this error from your program, specify the number of elements you want the array to contain.
