For some reason when using command line arguments to specify input
files, whenever I use 'gets' it seems to be reading from the argument
files instead of STDIN.
My code is something like this (simplified):
<code>
emp_file = ARGV[0]
inp_file = ARGV[1]
out_file = ARGV[2]
print "Please enter the first date of the pay period (MM/DD/YYYY): "
date = gets
puts date
exit
</code>
Now instead of allowing me to type a response it is just spitting out
the first line of the file that is given by ARGV[0]. In this case the
file is a list of 3 digit numbers and just spits out "###\n" and exits
without allowing me to type anything. Any ideas on why this is
happening? Do I need to clear 'gets' or something?
Thanks

I've seen a similar problem and I got around it by using $stdin explcitly
date = $stdin.gets
It might work??

It sounds like Ruby reproduces Perl's magical treatment of the commandline args. (Input is taken from the files listed on the command line, unles stdin is redirected.)
Perhaps you need to clear the ARGV array after reading the values out? For instance, use
emp_file = ARGV.shift
inp_file = ARGV.shift
out_file = ARGV.shift
instead of what you had above.
