"(XSCCOMP08) You cannot write into an aggregated VARIABLE dimensioned by a COMPRESSED COMPOSITE. Use the CLEAR AGGREGATES command to reenable write access."
*Cause: The user attempted to store a value into to a variable
dimensioned by a compressed composite, and the variable
had previously been precomputed using the AGGREGATE
command. Once the AGGREGATE command is run on a
variable dimensioned by a compressed composite, it
becomes read-only until the computed values are removed
with the CLEAR command.
*Action: Run the CLEAR AGGREGATES command to remove the computed
values from the variable and then rerun the failed
operation. Note that CLEAR AGGREGATES will remove all
the data computed during the last AGGREGATE command on
