Same syntax, different semantic and result

[qwerty]

Hey,

Can somebody tell me, why the first way is a working way, and the another is dead end? So it's working fine, after that the array looks good

		maps = GetCvar("scr_nextmap_maps");
level.nextmap["maps"] = StrTok(maps, ","); 
	

but in this case the array's size will be 0

		level.nextmap["maps"] = StrTok(GetCvar("scr_nextmap_maps"), ","); 
	

The question is why?
