c
c  purpose: To determine the format and file length required for the
c           transition strings of an ion
c
c
c subroutine:
c
c  input : (i*4)  ita_max   = largest value for transition index
c  input : (i*4)  isa_max   = largest value for transition multiplicity
c  input : (i*4)  ila_max   = largest value for transition orb. ang.mom
c  input : (r*8)  xja_max   = largest value for transition (stat.wt-1)/2
c
c  output: (i*4)  iw        = field length required for trans. strings
c  output: (c*63) fmt02     = appropriate format specification
