Go Up to Error and Warning Messages (Object Pascal) Index

This error message appears when you try to declare a set type of more than 256 elements. More precisely, the ordinal values of the upper and lower bounds of the base type must be within the range 0..255.

program Produce;
  BigSet = set of 1..256;  (*<-- error message given here*)

In the example, BigSet really only has 256 elements, but is still illegal.

program Solve;
  BigSet = set of 0..255;

We need to make sure the upper and lower bounds and in the range 0..255.
