A READ statement without the KEY option was attempted on a VSAM data set. This occurred after sequential positioning was lost as the result of a previous error during sequential processing (for example, read error on index set or failure to position to next highest key after a "key not found" condition). The ONCODE associated with this message is 1026.
The ERROR condition is raised.
Use the KEYTO option of the READ statement to obtain the keys of records read. Use this information to reposition a file for subsequent retrieval when positioning is lost.
