As the title states, this is my very first attempt at Obfuscation/JAPH so please don't be gentle with your comments. I had fun creating this and would love to hear constructive criticism that I can apply to my next attempt.

The program below has two functions:
1) If passed an integer (that represents a depth in feet) from the command line it will calculate the Atmospheres Absolute(ATA) for that depth (sea water is assumed).

2) If run without a parameter the program functions as a JAPH should.

This has been tested with v5.8 on Win32 and v5.6.1 on Linux.

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• 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).
