In IBM Cobol there are two methods of accessing elements in
a table (array). By subscript, which you explicitly define
in the Data Division or by index, which is implicitly
defined by the compiler.
01 subscript-for-table COMP PIC S9(4).
If you want the 20th item, set the above to 20 and use
field-looked-for (subscript-for-table).
An index is the displacement of an item from the start of a
table. For a subscript, the displacement, which is needed
to find the item, is calculated at run time (from the
subscript and the length of the data item(s)). So an index
is faster, but is generally considered more complex to use.
Some features, like SEARCH ALL, require the use of an INDEX.

In FIle 1 and FIle 2 , for matching Employee-DEPT (Only MECH) , we need to move entire records from file1 to file 2. We should not use 2D array. Your help is needed here.
