Hello Athanasius,

Thank you for your time and effort to assist me with my problem. I have updated the documentation and also the output of the code. Nice tips about the scalar @xls I was not aware the problem.

I am trying to process all arguments given with the extension -f test.xls -f test-2.xls -f test-3.xls etc.

I want to separate the -f option from the rest of the argument, in order to keep only the arguments with '*.xls' extension. But the tricky part is that I also need to take care of the last argument -p sample.csv. I was assuming by using the f=s{1,} in my script it will take only in consideration the -f arguments and ignore the -p arguments. Which it will simplify my target at least. But this is another challenge to over come.

Again thank you for your time and effort.
