radoulov's solution uses the gsub awk command, you say you can't use it - so what script are you using?

Correction, for strings <4 or >10 chars:

Code:
awk '
function min(a,b) { if (a < b) return a; return b }
{
  f = sprintf("%*-s", min(l,l - length + 3), substr($0, length - 2)) 
  gsub(/ /, c, f)
  print  f substr($0, 1, min(l - 3, length - 3))
}' l=10 c=X infile

Good point, I should have asked the OP to clarify how these case should be handled.
