IGZ0077W   The lengths of the data-item items in program program-name at displacement displacement were not equal. The shorter length was used.

The two data items which appear in a REPLACING or CONVERTING phrase in an INSPECT statement must have equal lengths, except when the second such item is a figurative constant. Because of the reference modification for one or both of these data items, the resultant length values were not equal. The shorter length value is applied to both items, and execution proceeds.
