counter in the loop should be local

[letypequividelespoubelles]

The inner counter of the loop should be local, ie for the moment we can't write

for i:u8=0; i<10; i=i+1 {
   do stuff
}
for i:u8=0; i<10; i=i+1 {
   do some other stuff
}

we have to write:

for i:u8=0; i<10; i=i+1 {
   do stuff
}
for j:u8=0; j<10; j=j+1 {
   do some other stuff
}
