How to use variables in vim command-like syntax?

Question

I want to write a function that can map a key to another function.

But I failed to insert the variables into map command:

map a:key :! a:action (in which a:key may be <F9>, <C-F9> and so on)

How to achieve this in vim command-like sentences?

Just for checking whether there is another way to go about this, what are you trying to achieve with this? — Rook

I want to write a function to map shortcut keys according to the file type. And I think it's better to make a function to avoid same code lines. — Determinant

If I understand your question correctly, you're looking for execute.

:execute "map " . a:key . " :!" . a:action

See :help :execute for more information.
