I have a script which I run using the following command line,what I noticed is people forget to add the options(-b,-l) and ran them without it.

finddata.exe -b file.txt -l data.txt

finddata.exe -b file.txt

finddata.exe -l data.txt 


I tried use the below but it fails when the tool is run as below


finddata.exe -b file.txt data.txt    (note the missing -l before data.
+txt).

if ($#ARGV < 1) {
print "USAGE";
}

Basically I want to make sure the optionsa re added.How do I that?
