Error PERL - Selecting specific files based on 'date stamp' values

Hi,

I've list of files in a directory, which have date stamp value in their names.

Code:
ex: 
abc_data_20071102.csv, 
abc_data_20091221.csv, 
abc_data_20100110.csv, 
abc_data_20100222.csv, 
abc_data_20080620.csv,... etc.,

I need to select and process only files, within the given date range.

Code:
ex: files starting from the date 20090101 to 20101231

I've written below scrtipt to select files starting from 'abc_data_' and ending with '.csv'.
This script is selecting all files starting abc_data_ and ending with '.csv'.

Code:
my @files = </test/ganap/abc_*.csv>;
foreach my $inputfilename (@files) {
   open( my $in_fh, "<", $inputfilename ) or die "Can't open $inputfilename : $!";
#.......................... file processing
}
close($in_fh);

Could any of you help me to achieve my selection criteria?Smilie
