TYPE: CHOP
TITLE: Hold CHOP

This CHOP allows you to sample and hold the value of the first input. The
second input controls the sampling. When the second input changes from 0 to 1,
the first input is sampled. This value is held in the output until the second
input changes from 0 to 1 again. Hold does not sample while the second input is
1, nor on the falling edge (1 to 0).

A common application of this CHOP is to grab the current value of a channel
when an event occurs, so that value can be used until the event occurs again.

This CHOP may be time sliced by enabling the Time Slice flag in the Common
page. It can also take advantage of Minimal Time Slice Cooks in time slice 
mode (see the Time Slice Preferences dialog in the Options menu).

This CHOP has no parameters or local variables.
