FMP-1028-00-F I-O error FMT1 DSCB

The error occurred executing an OPEN call instruction for a data set on a direct access device. An I/O error occurred reading the FORMAT1 DSCB. Or, the FORMAT1 DSCB for the data set could not be found either on the first volume specified by the DD statement, the volume indexed by the volume sequence number, or in the catalog.
Restriction: This topic applies only when the AppMaster Builder AddPack has been installed, and applies only to Windows platforms.

Resolution:

Inspect all INCLUDE statements for correct syntax and file specifications, and verify that the referenced file members exist. Also check DD statements for call libraries. If the FORMAT1 DSCB for the data set cannot be found, make sure that the DSNAME and volume parameters are correct.
