In first, with this :
//var %t = GA is Ga ,%b = $len(%t) ,%a 1 | while (%a <= %b) { var -s %r = $+(%r,$mid(%t,%a,1)) | inc %a }
all the spaces of %t will be removed in %r, why ? is it a bug ?
Other thing, : why can't we set a %var ( with /var ) if the var name doesn't begin with a % like :
//Var -s $+(%,a,b) 1
is it a bug too ?
