Hi Dmitry,

Thanks for the patch, it generally looks good. I have a few comments bellow.

Since you're changing all uses of StSep, I think it would make more sense to change StSep itself to accept multiple separator.

 x = 0
-Do While x < 2 : x = x + 1
+Do While x < 2 :
+x = x + 1
 Loop
 Call ok(x = 2, "x not equal to 2")

Please don't change existing tests like that. We want previous version tested as well. Add new ones instead.

Same here.

Thanks,
