Cascade TextLogger: Version 4.0
Prev |  | Next

# cache

cache -- Controls how frequently data is written.

## Syntax

    (cache y|n label [label ...])

## Arguments

`y|n`

  Sets caching on (`y`, which is the default) or off (`n`).

`label`

  A log or group command label.

## Description

The cache command lets you determine how frequently data is written. When caching is on (`y`, the default), data is written in blocks, according to your default C library file buffer implementation. When caching is off (`n`), each line of output is immediately flushed from the buffer to the file.

| If the Cascade TextLogger is started with the `-F` option, this command is ignored because there is no possibility of caching; all data is immediately flushed to the file.

## See Also

log, textlog

## Example

        (cache y temp press)
        (cache n max_ht min_ht)
