"Write once, run anywhere" is a cool motto that can't necessarily be true in practice. There are obvious O/S differences, such as drive letters on Windows, but there are less obvious differences which are hardware based, such as big-endian vs little-endian ordering, the way floating point numbers are represented (not all systems use IEEE arithmetic), basic code sets (EBCDIC vs ASCII; some older systems used 6-bit character sets), etc.
Quite a few languages try to achieve the nirvana of "write once, run anywhere;" it's not trivial for the people who build the underlying compilers|virtual machines|interpreters.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
