This question regarding Checkpoint.
Suppose my program has checkpoint for every 100 records. If
my program abends at 120 records, what will happen. I know
first 100 records are committed and rest of 20 records
where they gone and where they are stored.

As in anything else, it depends. If the buffers containing
your updates were written out, they are on your output data
set. Otherwise, they are lost.
The purpose of taking checkpoints is to allow you to
restart your program at the last known checkpoint, instead of
all the way back at the beginning. If your job ran for hours
and only had a few minutes to go, starting at the last
checkpoint can save a lot of time.
IMS will reposition your input and output files, so you can
pick up from there.
