IDF News: Making modifications to IDF programs or files
If you are making modifications to IDF programs or files, it is a good idea to create your modified objects in a test library that you create for this purpose.
The test library should be added to the top of the library list just after the temporary library QTEMP so your modified objects are found instead of the standard IDF objects. This test library allows you to make changes and test them, or to continue running in this mode permanently without actually replacing the original objects. This test library also helps you to isolate and control your modifications when applying patches from Infor.
