saving variables programmatically using list of variable names

Hi all,
This should be simple but I think my frustration level is keeping me from seeing the path.
I simply want to save some variables on the workspace based on a list of those variable names.
a=1;b=2;c=3
varNames = {'a','b','c'};
save('myMatFile',varNames)
which yields the error 'Error using save. Must be a string scalar or character vector'. (what must be a string scalar? File name? vars? Yes I know, vars, but still TMW...)
so how about
save('myMatFile',cell2mat({'a,','b,','c'});
yielding the more useful error 'a,b,c' is not a valid variable name.
I see where this is going, I must have a properly formatted string array akin to eval inputs. But there really should be an easier way, like my original attempt.
Thanks for the support and letting me rant a bit.
-Chris

That message does seem vague. I've reported that to the development staff.

Here is an easy solution:
a=1;b=2;c=3;
save('myMatFile.mat','a','b','c')
% Or
a=1;b=2;c=3;
MY_var = {'a','b','c'};
save('myMatFile.mat','MY_var')
