Rick,
Looks like you might be restricted by CA size and utility use...
from DFSMS Access Method Services for Catalogs, SC26-7394, DEFINE CLUSTER,
RECORDSIZE
When you use a record size that is larger than one control interval, you must
also specify spanned records (SPANNED). The formula for the maximum record size
of spanned records as calculated by VSAM is as follows:
MAXLRECL = CI/CA * (CISZ - 10)
where:
MAXLRECL is the maximum spanned record size.
CI/CA represents the number of control intervals per control area.
CA is the number of control areas.
CISZ is the control interval size.
Restriction: With REPRO and EXPORT, you cannot use data sets with record sizes
greater than 32 760.
