The program is written in the older fixed format. It conforms to COBOL
85 apparently.
Only a few changes are needed.
Put seven spaces before IDENTIFICATION DIVISION.
You need to add a PROGRAM-ID. paragraph.
The LABEL RECORDS ARE STANDARD clause is obsolete and should be
eliminated.
The RECORD CONTAINS 80 CHARACTERS clause is obsolete and should be
eliminated.
Don.t forget to put a period at the end of the FD lines in each case.
With these few changes the program as you submitted it compiles
without error using
cobc -x cobsamp.cbl
The corrected program is listed below. Note that DIVISION, SECTION, FD
and 01 headers begin with seven spaces. Named paragraphs begin with
7 spaces. Other lines in your sample begin with 9 spaces, but should
really begin with 11 spaces to conform to the old fixed format.

Of course the program will not run unless the two input files are
available.
To learn COBOL I recommend purchase of a good textbook, (in this case
the older the better) and of course study of the Open Cobol Manual
which is an excellent reference guide.
