Steve,

%dscompact wasn't introduced until DTM 4.3, so someone may have only
parially backported this utility from 4.3 to 4.2.  %dscompress has
changed over time, but generally it must run to completion or else
you have to restore from a backup.  If you have no backup you
should try a %dscompress in repair mode on the non-functional
dataset.  (%dscompress makes a repaired copy of the dataset whereas
%dscompact compresses it in place.)
