Sun / solaris / korn shell : reloading .profile, .kshrc

Well, I could have sworn there was an easy way to do this, but I have looked and looked )-:

How do I, using korn shell on Solaris UNIX, reload my .profile and .kshrc files without logging out and then logging back in.

For instance, let's say I add an alias to a file read by .kshrc and I want to use it without having to log out.

I tried using source, but it looks like I cannot use source.

The "dot" command was the original "source" command.

To add to that, if you don't have your present path in your $PATH and you want to source a local .profile, do:

. ./.profile

Just know that having "." in your $PATH is a security violation.
