Thank you for your correction. I just inserted the word 'explicit' to my question.

That implies that you still consider this an open question?

I ask, because I thought I answered your question even in its modified form.

Some commands take arguments: $you->doTheShopping( shoppingList ) requires the list.

(I'm aware that "retail therapy" can and often does rely entirely on impulse buying; but that's not 'the shopping' :)

Some commands don't need arguments: $you->comeHomeNow (Well, you can and often do try arguing, but where did it ever get you :)

Whilst some of that is humour, the point is serious.

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

"Science is about questioning the status quo. Questioning authority".

In the absence of evidence, opinion is indistinguishable from prejudice.

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).
Want more info? How to link or How to display code and escape characters are good places to start.
