[Maxima] string to identifier

[Adam Majewski]

How can I convert string to identifier ?

I would like to make a few list for draw package :
list1, list2 ...

for Denominator:1 thru DenominatorMax step 1 do
(
  name:concat("list",string(Denominator)),
  /* here I should convert string name to identier */
  name:Givelist /* my function */
);

TIA
