I have a source table that looks like the following "TestIN".

I want to read the file and create the output shown in TestOUT.

I assume it requires grouping and use of the Max function, but I don't know how to write the code.

I'm a newbie with no formal training, and any help will be appreciated.

Source Input File:  "TestIN"

Desired Output:  TestOUT
