There is paramanager.getintparaloc(), but you should try doing as much  
as possible at the node tree level rather than at the assembler level  
(especially calls). You can use caddnode.create(equaln,x,y) to create  
a comparison node, cstringconstnode.create() to create a string  
constant node, etc. The addnode will automatically select the proper  
comparison routine (shortstring, ansistring, widestring,  
unicodestring, <any future kind of string>) and insert necessary type  
conversions.
