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