How to pass Vim function argument to a command?

I'm using the following function + command to invoke the debugger in Vim:

function! TermDebugArm(executable)
    packadd termdebug
    let g:termdebugger="arm-none-eabi-gdb"
    Termdebug a:executable
endfunction

command! -complete=file -nargs=1 TermDebugArm :call TermDebugArm(<f-args>)

Unfortunately, the Termdebug command gets the literal argument "a:executable" and not the actual value it should represent (i.e. the filename passed to the command that called the function).

What am I doing wrong?

You need to use the :execute command to build a command from strings, which will allow you to use the value of a:executable as a literal:

execute "Termdebug ".a:executable

Or you can use the feature of :execute that will join multiple arguments with a space, so you don't need an explicit concatenation:

execute "Termdebug" a:executable

See :help :execute.
