In programming (and math) there are variables and constants. Is there a name to describe both of them? I was thinking value, but that's not it. A value is what variables/constants contain, not what they are.
I would call it a symbol. From google:
sym·bol/ˈsimbəl/Noun
1. A thing that represents or stands for something else,
esp. a material object representing something abstract.
