This is from the AppleScriptLanguageGuide.pdf:
A ï¬xed number of speciï¬c types of values are recognized by AppleScript. You
cannot deï¬ne additional types of values, nor can you change the way values
are represented. The different types of AppleScript values, called value classes,
are described in Chapter 3, “Values.”
No value has a property ‘proeprties’ where you can get its proerties. Some application objects have a property ‘properties’ where you can get the properties of the object. For instance, Finder has a prperty ‘properties’:
tell application "Finder"
If you want the properties of values see AppleScriptLanguageGuide.pdf. Here’s the old list of properties from the date class:
Class The class identiï¬er for the object. This property is read-only, and
its value is always date.
Weekday One of the constants Monday, Tuesday, Wednesday,
Thursday, Friday, Saturday, Sunday or Mon, Tue, Wed, Thu,
Fri, Sat, Sun.
Month One of the constants January, February, March, April, May,
June, July, August, September, October, November,
December or Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep,
Oct, Nov, Dec.
Year An integer specifying the year; for example, 1993.
Time An integer that speciï¬es the number of seconds since midnight
of the date value; for example, 2700 is equivalent to 12:45 AM.
Date A string that consists of the date portion of the date value; for
example, “June 3, 1993”.
For newer properties, you need to read the revision notes.
