Is the number of digits always 4? How many files will coexist in that directory? Is the number always incremented by one? The exercise will be to find the gap - if there is one - and start from above it, eventually using a solution like pamu's or raj_saini20's. I'm not sure if counting down from 9999 in a while loop is the best or most efficient solution, but it might do. You may want to check existence of 9999 and 0000 first as you can avoid the gap search if these don't coexist.
Easy solution if not more than a few file exist: ls -1 IN9*; ls -1 IN0*

SYSSTAT(5)							Linux User's Manual							SYSSTAT(5)

NAME

       sysstat - sysstat configuration file.

DESCRIPTION

       This  file is read by sa1(8) and sa2(8) shell scripts from the sysstat's set of tools.  It consists of a sequence of shell variable assign-
       ments used to configure sysstat logging.  The variables and their meanings are:

       HISTORY
	      The number of days during which a daily data file or a report should be kept. Data files or reports older than this number  of  days
	      will be removed by the sa2(8) shell script.

       COMPRESSAFTER
	      Number of days after which daily data files are to be compressed, either by gzip or bzip2.

       SADC_OPTIONS
	      Options  that  should be passed to sadc(8).  With these options (see sadc(8) manual page), you can select some additional data which
	      are going to be saved in daily data files.  These options are used only when a new data file is created. They will be  ignored  with
	      an already existing one.

FILES

       /etc/sysstat/sysstat
