Answer Posted / soumya santosini patnaik
first load the files in shorted order after that code a
matching program. in the procedure division check the file1
entry with file2 entry if file1 entry = file2 entry then
then write to o/p file end-evaluate esle check for file1<
file2 (if yes then the pointer is brought down to the 2nd
rec of file1 and checked with 1st rec of file2 when the
para is performed for 2nd time),if the above condition is
false then it checks if file1>file2 if yes then pointer is
brought down to the next entry of file2 and checked with
1st entry of file1 with 2nd entry of file2 in next perform
and the process is done till the end of records.
