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 C API function HI_Enable and the hist_enable dynamic library function.

Example

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