15AF: THE 'INITIAL CHANNEL INFORMATION'

Used by the routine at NEW, which copies the information from here to CHINFO. Initially there are four channels - 'K', 'S', 'R', and 'P' - for communicating with the 'keyboard', 'screen', 'work space' and 'printer'. For each channel the output routine address comes before the input routine address and the channel's code.
