Thanks, however, I simply meant my boolean 'ports' to mean a 'yes/no' control box of a 'data source', which, when selected, would signify a 'source' that could then be connected to a 'customer' port or 'receiving box'. Perhaps instead of port, I should have said input/output box.
My main question is simply about a data switch matrix of 20 inputs and 20 outputs. Should I attempt to manage the switching of data lines via cases, for loops, sequence, or what! I believe I will need to set up arrays, but controlling the matrix is ???. Thanks.
