Hi all,

I don't have much idea on COBOL.I got a req like:
Compare two files & write matching records to output file in COBOL.
file1: contains many records including a particular column of data.
file2:contains only that particular column of data.
i have to compare both the files and if a match is found in both the files i have to write the matching file to a output file3.



FILE1:
LFN102110211C357131839 1 C1301357131839
LFN102110211C357131839 2 C1302357131839
LFN102110211C357131839 2 C1302357131839
LFN102110211C357131839 3 C1303357131839
LFN102110211C357131839 3 C1304357131839
LFN102110211C357131839 3 C1303357131839
LFN102110211C357131839 3 C1304357131839
LFN102110211C357131839 4 C1305357131839
LFN102110211C357131839 5 C1306357131839
LFN102110211C357131839 7 C1309357131839
LFN102110211C357131839 7 C1310357131839
LFN102110211C357131839 7 C1309357131839
LFN102110211C357131839 7 C1310357131839


the data above in bold is the key data which will be used for the comparision with the below file.

FILE2:
53404B759
53404B809
53378A134
53378A175
533786240
533786265
53422F220
53422F238
533787115
533786257
534222799
