Re: Latitude to decimal degrees.

Roedy,

This ship above was a combined (latitude or longitude) calculation. I
needed this to deal with data that was shown such as Los Angeles County

34:04:45N 118:24:05W to the another form 34.07917 -118.40139

Here is the complete code below (at this time). While not shown here
will be features: name the location, radio buttons to detail whether it
is a latitude or a longitude, and the combining of the statements,
then a button to save as an append to a file.

This is output is used in another program to show the global (planet
Earth) distances between locations as the crow flies (ugh!), but which
lacks the MapQuest accuracy.
