COBRT195 DELETE/REWRITE not preceded by a read (Fatal)

Before a DELETE or a REWRITE statement can be successfully executed in sequential access mode the last input-output statement executed for the associated file must have been a successful read. In your code no read statement precedes your tried DELETE or REWRITE.

Resolution:

When your program has terminated, recode your program, making sure that the last input-output statement to be executed before the DELETE or REWRITE is a read statement.
