This Perl script converts between degrees of latitude and longitude and Maidenhead Locator grid specifications. Positions to convert are given as command-line arguments.

Any command-line argument that begins with a letter is assumed to be a Maidenhead Locator, and converted to degrees of latitude and longitude.

Any other command-line argument is assumed to be degrees of latitude, with south being negative. The following argument is taken as degrees of longitude east of Greenwich, England, with west being negative. The pair is converted into a Maidenhead Locator.

Output is to standard out.
