validating

Hi
      In the below code:
                EVAL      POO@#K = *BLANKS
                EVAL      POO@#K = %SUBST(BDGXX:5:1)
Iam extracting 5th position of BDGXX, now i want to validate this with one of 5 values A B C D E. When User enters anything other than that of these 5 values it should display a message in displayfile saying that "valid values are A,B,C,D,E only"... Please suggest various good ways to implement in RPGLE(not in display file).... 




Warm Regards,
JoeP
