If you need BASH features, use BASH. I don't think you can do that in plain Bourne.

I have to second Corona688 in that sh doesn't provide that.
But, you could exploit the local variables' features to build sth. alike of your own:
Code:
foo()
{ local FUN="foo $FUN"
echo $FUN
}

fooin()
{ local FUN="fooin $FUN"
echo $FUN
foo
}

FUN=$0

foo
foo sh

fooin
fooin sh
foo fooin sh

If a function called "main" is the caller, it will show up. In above, there is no "main"; sh as the basic shell is the caller, assigned to FUN when we do FUN=$0. Make that FUN=main if need be.
