Horizon and Prime Communication Programs HCP and PCP

Programs used to transfer text files between the mini-floppy diskettes on a North Star Horizon microcomputer executing the operating system CP/M-80, and a disk device on a Prime 550 minicomputer executing the operating system Primos rev 18.3 are described. The instructions to these programs defining the file transfers to be carried out are entered on the VDU of the Horizon by the operator via an option menu. Options exist to transfer files in both directions and to allow access to the Prime computer via the VDU on the Horizon. When an attempt is made to create a file which already exists the operator is asked to confirm or change the action.
