#1) APA reference for an online program.
Answer: The reference format for this follows your usual who-when-what-where format. Follow this bullet point and you should be fine. First use an individual’s name in the reference if he or she has proprietary rights to the program. In other cases, create a reference as you would for unauthorised works. After the title, in brackets, provide a descriptor for the item. This will help the reader immensely. If the software is available online, provide the URL rather than the publisher name and location.
These are examples:
Esolang, A. N. (2014). Obscure Reference Generator [Computer software]. Washington, DC: E & K Press.
Customized Synergy [Computer software].
