 Need Help??
With the help of, & grateful thanks to Gangabass, Athanasius, GrandFather, philiprbrenan, & ww. I offer my first proper Perl program to anyone who may like to use it. Cycle Gear Ratio Calculator
```#!/usr/bin/perl
use strict;
use warnings;

my \$fh = \*STDIN;    # For test input, change to: \*DATA
###my \$fh = \*DATA;    # For user input, change to: \*STDIN

print "\nMulti Gear Calculator\n\n";

print "Enter Wheelsize (inches): ";
my    \$wheel = <\$fh>;
print \$wheel;
chomp \$wheel;

print "Enter Chainwheel Teeth:   ";
my    \$chainWheels = <\$fh>;
print \$chainWheels;
my    @chainWheels = split /\s+/, \$chainWheels;

print "Enter Cog Teeth:          ";
my    \$cogs  = <\$fh>;
print \$cogs;
my    @cogs  = split /\s+/, \$cogs;

print "Wheelsize:   \$wheel\n";
print "Chainwheels: @chainWheels\n";
print "Cogs:   @cogs\n\n";

for my \$chainSel (1 .. @chainWheels) {
my \$wheelMul = \$wheel * \$chainWheels[\$chainSel - 1];

print "Chain wheel: \$chainSel ratios:  \n";

for my \$cogSel (1 .. @cogs) {
printf "%5.2f  ", \$wheelMul / \$cogs[\$cogSel - 1];
}

print "\n";
}

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

• Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
• Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
• Read Where should I post X? if you're not absolutely sure you're posting in the right place.
• Posts may use any of the Perl Monks Approved HTML tags:
a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
• You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
 For: Use: & & < < > > [ [ ] ]
• Link using PerlMonks shortcuts! What shortcuts can I use for linking?
