sources (Table)

To enable cross-channel writing (only), there is a global table sources.

This table enables access to the protocol table for each channel.

For example, for channel 1, use sources[1].

To write to channel 1:

source.write(sources[1], "Hello")
--or--
sources[1]:write("Hello")

[!note[
If you wish to write out through this channel's source then within a protocol script you can use the abbreviated form: p:write(“Hello”).

However, since the onrecord event is not passed the protocol table you must use the expression source.write(sources[c], “Hello”) (where c is the channel number that is passed to the onrecord event.)
