This only occurs during compilation if the compiler recognizes a statement that is trying to move an illegal value into a numeric field as this is not allowed. So if you have something like: 01 my-group. 05 num-field pic 9(5). 01 aspace pic x value space. and you try: move space to num-field * you will get zero substitution because compiler knows illegal value but if you use instead the data-item aspace move aspace to num-field * no compiler error but you may get rts163 error at run-time. if test for 0 fails if you move spaces to the group item you will not get compiler error but may get rts163 error at run-time but if test for 0 fails move space to my-group if num-field = 0 display "yes" else display "no" end-if
