WRITETHRU

The WRITETHRU option determines whether modifications to a file are written out to disk immediately or buffered internally, either by the COBOL system or by the operating system, and flushed to disk at a later stage.

Syntax:
WRITETHRU={ON|OFF}
Parameters:
ON Write out all modifications to disk immediately.
OFF Flush modifications later.
Properties:
Default: OFF
Comments:

You can obtain greater security, at the cost of significantly reduced performance, by setting this parameter to ON.
