Programed vs. Programmed
“Programmed” and “programed” are both recorded inflections of “program.” Cambridge displays the double-m form, while Collins also lists the single-m variant, so this is a spelling-choice issue rather than a difference in meaning.
Both forms are recorded. Cambridge displays “programmed”; Collins also records “programed.” Use the form required by your house style and stay consistent.
