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 and being connectable to an image forming device that is configured to execute a formation operation of forming image data, 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 type information, the type information indicating each type of the plurality of external programs;
• determining whether the corresponding external program is a first type or a second type based on the obtained type information, the first type indicating the external program that is to be activated before execution of the formation operation, the second type indicating the external program that is to be activated after the execution of the formation operation;
• pre-processing of activating the external program, which is determined as the first type, and obtaining a parameter indicating a condition of generating the image data designated by a user;
• and
• generating the image data in accordance with the parameter obtained in the pre-processing, the generation of the image data comprising:
• instructing the image forming device to execute the formation operation;
• and
• performing post-processing of activating the external program, which is determined as the second type, with designating the image data formed in the formation operation.
