I have string that displays the sum of various numbers. The string is concatenated in a loop. However, at the end of the calculation, an extra "+" displays. How can I remove that plus sign?
ie.
2+5+7+9+10+=33
How do I remove the last + sign? Thanx.

maybe you're just exiting the loop too late.
try exiting the loop sooner so that the "+" wont show up at the end of your equation

code: 
function Sum_Of_The_Proper_Factors (I_number : int, B_flag : boolean) : int
%This function calculates the sum of the proper factors of a number
%The function requires the number
%The function returns the sum of proper factors back.
var I_sum : int := 0
S_factorsString := ""
for I_factor : 1 .. (I_number  1)
if I_number mod I_factor = 0 then
I_sum := I_sum + I_factor
S_factorsString := S_factorsString + intstr (I_factor) + "+"
end if
end for
result I_sum
end Sum_Of_The_Proper_Factors
S_sumOfFactorsString := intstr (Sum_Of_The_Proper_Factors (I_number,
B_flag))
GUI.SetText (I_factorsOutput, S_factorsString + "=" +
S_sumOfFactorsString)

im not good at programming, but logically speaking, y dont u just forget about displaying the "+"s?
u can put a space or sumthing instead

you can use substrings to get rid of the last character (the unwanted +)
word := word(1..*1)
then you add "= whatever"

Or, don't append the plus sign... do an if statement for it
code:  for I_factor : 1 .. (I_number  1)
if I_number mod I_factor = 0 then
I_sum := I_sum + I_factor
S_factorsString := S_factorsString + intstr (I_factor)
%
if I_factor (notequal) I_Number  1 then
S_factorsString := S_factorsString + "+"
end if
%
end if
end for 
notequal: I forgot the operator for it. ~=?
