Good point. == and = are both relational operators. == is the actual test for equality. = works only in CAS and establishes an equation, which when used as an expression evaluates to true if and only if CAS can show that the left and right sides are the same.

<> and ≠ behave similarly.

A single = also works as a test for equality in non-CAS mode. Maybe it's not supposed to work but it does. Try it.

Code:

A:=5;
REPEAT
  PRINT(A);
  A:=A-1;
UNTIL A=0;
END;
