Directive #forceref: What's it's effect?

[rudi]

Hi.

Reading the help file I noticed the directive "#forceref" in sereral sample codes, e.g. for "ByRef" in this line:

#forceref $v1, $v2, $v3, $v4, $v5, $v6, $v7, $v8, $v9, $v10, $v11, $v12, $v13, $v14, $v15, $v16, $v17, $v18, $v19

What is it's effect? searching the help file, I can find it "outside" of sample code just for this entry:

Au3check syntax tool

#forceref $varname [, ...]

can be used for inside functions, like the following:
Func Test_Numparams($v1 = 0, $v2 = 0, $v3 = 0, $v4 = 0, $v5 = 0, $v6 = 0, $v7 = 0, $v8 = 0, $v9 = 0)
#forceref $v1, $v2, $v3, $v4, $v5, $v6, $v7, $v8, $v9

Same question for #forcedef

From this postings here I don't get the exact effect either:

(#forceref)

(#forcedef)

This directive make Au3Check "think" the variable has been referrenced even when it wasn't. This is to suppress a message when flag "-w 5: local var declared but not used (off)" has been set to on.
