Abstract: A programming assistance apparatus assists programming with respect to a program that operates two or more devices including at least a robot in parallel. The programming assistance apparatus includes a device extractor, a determiner, and an alerter. The device extractor extracts an identification name of a device to which an operation command is issued per unit of parallel operation based on a description content of the program. The determiner determines whether there is a shared target device, to which operation commands targeting a same device in two or more parallel operations are issued. The alerter outputs an alert when it is determined that there is the shared target device.
