Creating LF over flat files

Given example creates a structure without affecting the existing flat file. It defines the structure and key fields over the flat file.

This way, you will be able to use the flat file as if it is a structured file.

Step 1: Create flat file.
CRTPF FILE(TESTPF) RCDLEN(80)

Step 2: Consider this flat file stores information for two fields (1-10) & (11,80). Now create Lf over test pf.
