Re: [ferret_users] string variables and format statements

[Ansley Manke <ansley.b.manke@xxxxxxxx>]

Another thought, Ned.  You can skip lines in your file by defining a 
second variable with the "strides" syntax.

 set data /var="v1_in,v2_in"/form=delim  my_file.txt
 let npts = v1_in[i=@ngd]
  let v1 = v1_in[i=1:`npts`:5]
  let v2 = v2_in[i=1:`npts`:5]
