Well, second attempt. :-)

I need datatype witch can store some unknown amount  of  elements.
Elements must be referensed by  index.  Time  for  referencing  is
critical parameter.

In C i can use array of pointers  for  that  purpose,  start  from
some size  and  realloc()  it  on  need.  In  scheme  vectors  are
applicable for that with one small exception -- they can`t  change
size.
