[Swift-user] two questions about Swift

[Zhao Zhang]

Hi, Yi

There is a "Iter" in swift, which could work as a while statement. I am 
attaching an example.
And it is also in swift documentation.

scipiter (scipin infile, scipopts settings)
{
 scipout ofile[] <ext; exec="mapout.sh", t=@infile>;
 scipin infilearray[]  <ext; exec="mapin.sh", t=@infile>;
 scipopts f <single_file_mapper;file="template">;
 //infilearray[0]=infile;
 iterate i {
     ofile[i]=scip(infilearray[i], settings);
     infilearray[i+1]=parser(ofile[i], f);
 }until(i==9);
}
