DBTT clause

BALTER cannot process compressed records, i.e. it cannot perform decompression, reallocation, sorting or deletion.

If the ORDER clause in the new schema is LAST, FIRST, NEXT, PRIOR or IMMATERIAL, the linkage method in the MODE clause may only be modified if no records of the member record type are stored.
