[PATCH 2/4] vbscript: Implemented Sgn(try 5)

[Piotr Caban]

Hi,


+Sub testSgnError(strings, error_num)
+    on error resume next
+
+    Call Err.clear()
+    Call Sgn(strings)
+    Call ok(Err.number = error_num, "Err.number = " & Err.number)
+End Sub
+
+Call testSgnError(Null, 445)
This test fails on windows. Tests needs to pass both on windows and on wine.

+    if(V_VT(arg) == VT_NULL) {
+        FIXME("Null argument not supported\n");
+            return E_NOTIMPL;
+    }
Please fix the indentation here.

Cheers,
Piotr
