Hi kitwei,<br />
This question is a repeat of question Q_10300771, which was asked (and answered) before this one appeared.<br />
<br />
What test do you want to do on the data?<br />
ozo and I assumed you wanted to know whether or not it _was_ a number, and scudweb assumed you wanted to know if it contained a digit (0-9) anywhere within it.<br />
e.g. my test would regard &quot;1234&quot; and &quot;12 &nbsp;34&quot; as different, but scudweb's test would regard them as the same.

I have though of a better example<br />
&nbsp; &nbsp;&quot;1234&quot; and &quot;&gt;/34&quot;.<br />

I have though of a better example
   "1234" and ">/34".

don't worry, I'll try all cases, I'm learning Perl, so I don't mind getting more info and giving away pts

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.
