0x00810034 (8454196) This type of IAM file cannot be referenced in USE grammar.

Explanation
A file was tentatively identified as an IAM file. However,
the information that was returned from the SHOWCAT macro does not identify
the file type as a cluster or path. 

User response
Ensure that the cluster name for a KSDS or ESDS data set
or the path name for an IAM alternate index is referenced.
