current shell funcitons

I have a program called persfuncs that contains a few simple functions.  I added it to my .profile using ". persfuncs" but the functions are not in my curent shell.  If I run it at the command line it will be available.  How do I get these functions into my current shell?  Oh, one more thing, I tried to add the functions directly into my .profile and it still did not work.

Thanks
Chris

I guess you are using ksh, true?

The .profile is used for variables etc and sourced when you login.
For interactive execution (like opening a new xterm) it expands the ENV variable (usually soemthing like .env, .kshrc) and executes it. That's where you put your interactive functions in ...

Another option is to create a directory to hold your functions, put it in your FPATH (like PATH, but for functions), and put the definition of each function in a file in that directory that has the same name as the function.

Bourne Shell has no functions.  I'll assume you mean POSIX J shell or System V shell, both of which are derivatives of Steve Bourne's original shell that were shipped with commercial Unix systems as /bin/sh.

POSIX J shell works the same as ksh, but only if you use the
  function name {
  ...
  }
syntax.

System V shell has functions, but only the
   name() {
   ...
   }
type, which don't work with FPATH, and this shell doesn't have
ENV either, so there's no way of doing this in System V shell.

If your system isn't running POSIX J shell as /bin/sh, then
you'll need to use a more modern shell like ksh or bash.

  You can put the functions in your .profile. or if you are using ksh, put them in the .kshrc file, and add the followings to your .profile:
   export ENV=$HOME/.kshrc

If bourne shell does not have functions then why is it that if I enter funciton_name () { .....;} it works.  And if i put it into a script and execute it in the current shell it works....but not in the profile? I'm lost on this one.

Because you're not using Steve Bourne's Bourne Shell from Bell Labs.
You're using System V Shell, which added the syntax you describe.
This is shipped as /bin/sh on Solaris and (I think) IRIX.
HP-UX ships POSIX J Shell as /bin/sh, and AIX ships KornShell
as /bin/sh.

I'm am using Solaris, so that explains it.  Now back to how do I get it to execute in my .profile in order to use it in my current shell.

You don't.  You can't do that in Solaris /bin/sh.  Use ksh or /usr/xpg4/bin/sh (which is actually a symbolic link to ksh).
