You are processing an input file in a Natural program and you
want the program to fail if the file is empty. What command you
use in Natural to force it to fail ?
Answer Posted / jaishree
You use the following steps to check whether the input file
is empty
Step A. Read work file #WK-Number once #WK-Record
Step B. At End of File
Write "Input file is Empty"
End-Endfile
The first step will read the first record in the file and
the next step will see the End of File condition. If the
File is empty, the program will write that we have an Empty
input file to spool.
