Best approah for mapping two files

Hi All,

In my project I have requirement to read the record from from .txt file and replace characters at different byte position with another file.

for example from file1.txt read a record1 and replace character at position 0, 1, 4 , 7, 9, 10 and so on with record1 from file2.txt.

can any one suggest any good approch to get this done.
