And use this in an IF-construction.

If you try EVALUATE(intVar,"text") and you don't use the IF-contrsuction, you will get a runtime error because "text" is no integer.

intVar: integer;
strVar: text[30];

strVar := '6';
IF NOT EVALUATE(intVar,strVar) THEN BEGIN
    // this code will not be executed
END;

strVar := 'test';
IF NOT EVALUATE(intVar,strVar) THEN BEGIN
    // this code will be executed, because 'test' cannot be converted to integer
END;
