I have a physical file FILE with fields A, B and C. I am using these fields as KEY fields in logical file FILELF. But in my program, i have scenarios like:-
a. Read FILE on the basis of key fields A ,B and C, if not found then
b. Read FILE on the basis of key fields A,B or A,C or B,C, if not found then
c. Read FILE on the basis of key fields A, B, C
I have made the steps like this.
FILELF with key fields will handle, ABC, AB and A
but for scenarios like B,C and AC and C, i am bound to create three more logical files.
If anyone out here to sort this out with the minimum number of logical.
