If we put three reads in COBOL in the same para one after the other, to read a PS file,will it read the same record thrice or it will read three records sequentially?
For example :
Input File
01
02
03
Para 900
Read infile
Display Infile rec
Read infile
Display infile rec
Read infile
Display infile rec.
What will be the output?
