RE: Test a field for specific values only

["Morgan, Paul" <Paul.Morgan@xxxxxxxxxxx>]

If a blank is also valid (but OP says only A or N) then include a blank in the comparator: 

%CHECK( 'AN ' : YourField ) <> 0

Hi Jeff, You're right:

If YourField = 'AA'  
 Pos = %CHECK(C_AN :YourField); // Pos = 3


So try:

D C_AN          C                   'AN'
D YourField       S             20
D wkVar           S             20    Varying

     wkVar = %Trim(YourField);
     If %CHECK(C_AN : wkVar) <> 0;
         //Error
     Endif;

That does not work if the field is AA or NN.
Each position of the field can only be A or N.
