In my 25 years in Pick I have never seen a construction like this to test for Y 
or N or whatever it's doing.
What is this doing?  What is this 1]2 and <1,1> doing ?  Why do I need this?


0297: CHECK:   PRINT @(0,17): "Are the problem codes correct (Y/N)? " :
0298:          INPUT ANSWER
0299:          LOCATE ANSWER IN '²Y²N²1²2'<1,1> SETTING TEST ELSE PRINT BELL
0300:          LOCATE ANSWER IN '²Y²1'<1,1> SETTING TEST ELSE
0301:             PRINT @(0,13):CLEAR.REST.SCREEN ; GOTO ENTER.PROBLEM.CODES
