When possible, avoid the use of acronyms.
Acronyms can create confusion, especially when several are used in the same context.
When used, acronyms should be capitalized without periods or spaces. It is preferable to spell out the names of countries and federal agencies, abbreviating or using acronyms only when space is limited and then with periods. Computer software and programs often are referred to by acronyms, capitalized and without periods. Some program names consist of two words run together, with initial caps. Refer to manufacturer preference.
