I think using lines(-1000) or a similar solution is not a good solution
because as I said lines function does not rules the display of a single
variable, but the display of all output generated by an instruction

In my opinion it should be better to extend the format function adding
an optional argument or modifying the function to allow syntax like
format("type","v","digits",10,"max_lines",100)
format("max_lines",100)
