Dear Experts,<br />
<br />
Objective: to store user input $1 and $2 in two different variables<br />
<br />
Goal: execute the script with the below command<br />
<br />
#prodcredclnt.pl U12345 25.00<br />
<br />
Question: How do I store U12345 into a variable $acctnum and 25.00 in a variable name $diffamnt?<br />
<br />
My poor attempt:<br />
@arr = &lt;STDIN&gt;<br />
$acctnum = $arr[0];<br />
$diffamnt = $arr[1];<br />
<br />
Question: what is the easiest way to accomplish this?<br />
<br />
Many thanks for your help,<br />

Perl is a high-level, general-purpose, interpreted, dynamic programming languages with over 25 years of development. Perl 5 runs on over 100 platforms from portables to mainframes and is suitable for both rapid prototyping and large-scale development projects.  Perl gained widespread popularity as a Common Gateway Interface (CGI) scripting language, in part due to its regular expression and string parsing abilities. In addition to CGI, Perl is used for graphics programming, system administration, network programming, finance, bioinformatics, and other applications.
