See ?deparse . E.g. (with several stylistic improvements)
func <- function(a)
cat(sprintf("Anova for variable %s\n",
sQuote(deparse(substitute(a)))))
func(Age)
Note that you expliciltly do not want the *vaiue* of 'a', but the symbol
passed. That is non-standard behaviour, and you might want to consider
why func("Age") is not a better way to do this.

'S Programming' (see the R FAQ).
I have a function definition:
Well, that is not a function definition: please do use correct and
reproducible examples as the posting guide asks.
func(a)
cat("Anova for variable ",a)
What I wish to achieve is to call func with a value such as:
func(Age)
and then obtain:
Anova for variable Age
Using "names(formals())" inside function func yields "a". That is not what I
need. I need the name contained in a, which in this case is Age.
Thanks for your time.
