enable

enable -- activates data recording.

Syntax

(enable [pattern])

Parameters

pattern: The name of one or more (using a globbing pattern) histories previously defined by the history command. When this parameter is not specified, the default is *, to include all histories.

Returns

t (true) if successful, otherwise

    (error "No history matching pattern")

Description

This command reverses the effect of a previous disable, hist_disable, or HI_Disable call, so that new data values will be accepted and logged.

This command corresponds to the Cogent API function HI_Enable and the hist_enable dynamic library function.

Example

    [sh]$ lsend Hist
    Hist> (enable p5)
    t
    Hist>
