Hi,

Please help me in acheving the below mentioned requirement.

1.We have 2 Input Files and one Output files.
2.The order of the records written in the Output File will remain same as the Input File 2.
3.For each Matching key in the Input File 2 we need to replace first 3 bytes with the string ‘PRD’ and 4 – 11 bytes with the string present in Input file 1 starting at 9 Position till 8 bytes. The changed record is written in the output file
4.Non matching records are untouched and written as it is on to the output file.

The belos is the sample input and output data.

Input File 1: (1- 8 is the key ( 8 bytes),FB=80)
----------------------------------------------------------------------------------------------------
Tstkey11Tstkey12
Tstkey21Tstkey22
Tstkey31Tstkey32

Input File 2: (104 - 111 bytes is the key ( 8 bytes),FB=111,First 11 bytes is spaces)
