[bug-gawk] How to mimic inserting an element to a vector?

[Peng Yu]

Hi,

I use the following code to mimic inserting an element to a vector
(i.e, the keys are 1,2,...). But it is a little cumbersome. Is there
any implement that is better?

function insert(a, i, v) {
  for(k in a) {
    if(k>=i) {
      a[k+1] = a[k]
    }
  }
  a[i] = v
}

BEGIN {
  for(i=1;i<=3;++i) {
    a[i] = 100 + i
  }
  PROCINFO["sorted_in"] = "@ind_num_desc"
  insert(a, 2, 2)

  PROCINFO["sorted_in"] = "@ind_num_asc"
  for(k in a) {
    print k, a[k]
  }
}
