I want to match the two files and for matched records i want to overlay One FIELD from File2 to File1...
After every RUN, the Overlaying field will be offset by 10 bytes..
For example ,
for first run file 1 - overlay field - 10-10
for second run file1 - overlay fields- 20-10
but the offset value will be fixed.. as 10..
Please help me to update the position in OUTREC automatially.
