vfp8 parameters and variable question

hi all.
i am new to foxpro programming.
I am not sure that this is the best place for my question but i am not able
to find "working" newsgroup and/or forum about foxpro (btw, any hint
appreciated) .

my problem: I have a form defined procedure and would like to call it and
receive 2 parameters back.
i tried with: thisform.myproc(parm1,parm2) but it does not work (i read that
in this way the parameter are passed by value and not by ref...)
so i tried with DO thisform.myproc WITH (parm1),(parm2) ... but it does not
work...myproc is not recognised (even without thisform.)
so what can i do???
i tried with global variables and it worked but i do not want to use global
variable for this kind of stuff...but...it is not possible to define the
variable scope for the form? only for the procedure itself or global seem to
be the possibilities...

if somebody knows other resources for my problem, plese let me know.

thanks and ciao.

You already answered the question: pass the values by reference.

lcVal1 = ""
lcVal2 = ""
thisform.myproc(@lcVal1, @lcVal2)
?lcVal1, lcVal2

* form method:
FUNCTION myproc
LPARAMETER tcVal1, tcVal2
tcVal1 = "1"
tcVal2 = "2"
ENDFUNC

Along with what Eric wrote it is also common th use custom form
properties. ie.
thisform.lcVal1 = ""
thisform.lcVal2 = ""
