Yes. I in fact do. I ran a test before I posted.

Here is the program for Ver 5:
--------------------------
byte a;

sub void main(void){
a = foo;
}

function byte foo(void){
a = 1;
return(6);
}
--------------------------

Here is a subset of the instructions generated by the ver 5 compiler:
--------------------------
----:<@Call#1-Exit>: After foo is called.....
0030:111 '->foo This is where 'a' gets assigned to 'foo'
0031:247 'GetVariable
0032:110 '->a
0033:246 'Setvariable
0034:129 'Branch
----:<main-Exit>:
----:<foo-Begin>:
0035:001 'Number This is where 'a' gets set to 1.
0036:110 '->a
0037:246 'Setvariable
0038:006 'Number This is where foo gets set to 6.
0039:111 '->foo
0040:194 'Let Value
0041:129 'Branch Return from the function....
----:<foo-Exit>:
--------------------------

Works just like it should.
