Non-transitory computer-readable medium and portable device

A non-transitory computer-readable medium having a computer program stored thereon and readable by a computer of a portable device, the portable device comprising a memory, a display and an input interface and being connectable to an image input device configured to execute an input operation of transmitting input data, which is input in accordance with an instruction of the computer program, to the portable device and to an image output device configured to execute an output operation of transmitting output data designated by the computer program, the memory storing a plurality of external programs that can be activated by the computer program, the computer program, when executed by the computer, causes the portable device to perform:

• obtaining function information, the function information indicating a function of each of the external programs;
• displaying a first screen on the display, the first screen comprising a plurality of first objects each of which corresponds to each of the plurality of external programs;
• receiving a user operation on the first screen through the input interface;
• in response to the first object being designated in the receiving of the user operation on the first screen, determining whether a designated program, which is the external program corresponding to the designated first object, has one of a first function and a second function, based on the function information of the designated program, the first function being a function of executing processing for the input data, the second function being a function of enabling a user to designate the output data;
• in response to it being determined that the designated program has the first function,
• instructing the image input device to execute the input operation;
• and
• performing first post-processing of designating the input data input in the input operation and activating the designated program;
• and
• in response to it being determined that the designated program has the second function,
• performing pre-processing of activating the designated program to obtain the output data;
• and
• controlling the image output device to execute the output operation for the output data obtained in the pre-processing.
