This document describes the ADASAV utility functions added specifically for use with the Delta Save Facility. The functions are:
combining "offline" delta save output, either alone or with the last full save output;
combining "online" full or delta save output with data from the corresponding DSIM data set;
unloading the DSIM data set to a sequential delta save data set.
RESTORE DELTA for restoring a full save and delta save output without a prior merging;
With the exception of `SAVE database', these functions are only available when the ADARUN parameter DSF=YES is specified. The `SAVE database' function includes special processing when DSF=YES is specified.
