can someone tell me the use of += and -= operators (SOLVED)

-----------------------------------

ive seen this in some programs but i do not know how/what it does exactly.... ive looked in turing help under operators... and i searched but no luck in finding it...

hehe...
+= is the same as something:=something + something else
-= is the same as something:=something - something else
so

number:=number+1
%is the same as%
number+=1

number:=number-1
%is the same as%
number-=1

mebbe it's only in C++ but you could also try

*= and
/= 
and see if they work as well

actually in turing , it works quite well ... i was initially going to reply that even (+=) doesn't work .. but i would have made quite a fool of myself , wouldn't i!? any way ... it works

yeah, cervantes uses that a lot and i never understood his code until i understood that. anyways, i wish turing allowed var++ or ++var cause that is SOOOOOO easy. hehe, anyways, everyone go and check out "shadows collide with people" by john frusciante
