high() and low() accept expressions

Original Reporter info from Mantis: kays @KaiBurghardt

• Reporter name: Kai Burghardt

Description:

high() and low() accept expressions, but should only accept ordinal and set data types, or array and set variables

Steps to reproduce:

program dependentRangeDefinition(input, output, stdErr);
type
	foo = 0..7;
	// Note, this was an accidental programming error of mine:
	bar = 0..high(foo * 6);
begin
	writeLn(high(bar));
end.

Additional information:

The maximum value an expression may assume is usually of minor interest, since we already know it is the processor’s native type.
