Arc/Info Users can use the FREQUENCY command to derive an INFO file of statistics from a coverage. Run a frequency on proj_coqdsfed.pat and name the resulting file proj_stats:
Arc: frequency
Usage: FREQUENCY <in_info_file> <out_info_file> {case_item}
Arc: frequency proj_coqdsfed.pat proj_stats
Enter Frequency item names (type END or a blank line when done):

Enter the 2nd item:
