Name:

rtrim$() -- trim spaces at the right end of a string

Synopsis:
 
a$=rtrim$(b$) 

Description:
The rtrim$-function removes all whitespace from the right end of a string and returns the result.

Example:
input "Please answer 'yes' or 'no' : " a$ 
a$=lower$(ltrim$(rtrim$(a$))) 
if (len(a$)>0 and a$=left$("yes",len(a$))) then 
	"Yes ..." 
else 
  	print "No ..." 
endif 
Explanation:

This example prompts for an answer and removes any spaces, which might precede the input; therefore it is even prepared for the (albeit somewhat patological case), that the user first hits space before entering his answer.
