Hi Folks... I hope this isn't asking too much. I have found using the
docs to be less than satisfying when trying an alternative coding
technique. I guess I fall into the old dog, actually the old
Hypercard dog, trying to learn the new Rev tricks.
I just wrote a quick and dirty script to parse out an iCal calendar
saved as a text file to feed my car expense calculator which was
published a few months ago in a Rev newsletter. The script is very
slow and I was intrigued to know how to speed it up as I am aware that
I am using very archaic scripting techniques.
Here is my script. It's relatively short and contains almost all of
my favourite coding patterns. If anyone has the inclination, perhaps
you could point out how I might make use of Revs improvements over
Hypercard...
It has to do with better ways to handle repeating actions and better
ways to handle lists... Thanks in advance... Jim
