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.
