Extracting Text Using Offset and Reverse vs Text Item Delimiters
There are times when you want to extract part of a text string from another for some specific purpose. There are two basic methods and each has its advantages and disadvantages. We’ll start with a combination of offset and reverse to remove the suffix from “seattleSunset.jpg”:
set jpgFile to characters of "seattleSunset.jpg"
–This gives us the characters as a list: {”s”, “e”, “a”, “t”, “t”, “l”, “e”, “S”, “u”, “n”, “s”, “e”, “t”, “.”, “j”, “p”, “g”} set jpgFile to (reverse of jpgFile) as string
–>result: “gpj.tesnuSelttaes”
Or we can combine the statements into one:
set jpgFile to (reverse of characters of "seattleSunset.jpg") as string
–>result: “gpj.tesnuSelttaes”
Next we extract the file name without the prefix:
set periodDelimiter to offset of "." in jpgFile
set jpgFile to text (periodDelimiter + 1) thru -1 of jpgFile
–>result: “tesnuSelttaes”
set AppleScript's text item delimiters to {""} –we must reset the item delimiters to empty for this to work correctly set jpgFile to (reverse of characters of jpgFile) as string
–After resetting the item delimiters, we use the same syntax as above.
First, remembering that what is in parentheses is performed first, jpgFile is coerced to list form and converted to the reverse order.
Then it is coerced back to a string: “seattleSunset”
If we start withset jpgFile to characters of “seattleSunset.jpeg”we still get the result: “seattleSunset”
Note that we could set the text item delimiters to “.” to get the same result:
set AppleScript's text item delimiters to "."
set jpgFile to text item 1 of "seattleSunset.jpg"
–>result: “seattleSunset”
The problem with this method is that if we have something such as“http://www.scriptsforapple.com/”(my website), the result is: “http://www”, which is probably not the result that we want. The original version, however gives us“http://www.scriptsforapple”which is useful if we want to change“.com/”to“.org/”:
set AppleScript's text item delimiters to "."
set theURL to "http://www.scriptsforapple.com/"
set AppleScript's text item delimiters to {""}
set trimURL to (reverse of characters of theURL) as string
set periodDelimiter to offset of "." in trimURL
set trimURL to text (periodDelimiter + 1) thru -1 of trimURL
set trimURL to (reverse of characters of trimURL) as string
set theURL to trimURL & ".org/" –>”http://www.scriptsforapple.org/”
The point here being that if you use this method, you can get the correct result for many, if not most, cases that you will encounter. That is not to say that there are not times when using text item delimiters alone will not be the right way to go depending upon the situation.
If you are more of a techy kind of person and are comfortable with using Terminal, here is a script you can use to easily create multiple folders:
First, for a single folder, type in: mkdir "Folder 1"
--or whatever you want to name your folder, this creates a new directory, which, in effect is a new folder.
To place multiple items in the 'Documents' folder:cd/Users/Administrator/Documents
mkdir "Folder 1" "Folder 2" "Folder 3"To quickly create multiple folders, create a text file with the desired folder names (as many as you want) and name it something like 'folderList.txt'. Next type this in Terminal:cat folderList.txt |xargs mkdirOr you could create folders with the same prefix by entering:mkdir "Invoices " {"Corporate", "Individual", "Pro-Bono"}

Heres an AppleScript for backing up a selected group of HyperCard files. this was used in one of my HyperCard stacks, but could be adapted for use in OSX programs with little or no modification:
send "suiteBkp(true)" to bg btn "BackupSuite"
--Use this line to call the handler below (true displays a notification dialog when the process is complete, you must have a button named bg btn "BackupSuite"):
on suiteBkp(theBoolean)
copy line 1 of field "selectedFolder" to theHFFolderPath --You'll need a hidden field named "selectedFolder" that a script (prior to the call) will place the path to the desired folder in.

Here's a simple, but very useful little HyperTalk script for verifying the validity of a date entered by a user, assuming that you have a menu item "flag date..." (or whatever you choose to name it) or it could be altered slightly and placed within a mouseUp statement:
if menuItem = "Flag Date..." then
global tryDate
ask "Enter a date for your new appointment:" with the long date
if it ≠ "" and the result ≠ "Cancel" then
put it into tryDate
else
put "" into tryDate
exit doMenu
end if
if invalidDate() then
answer "The date entered is not valid!"
put "" into tryDate
exit doMenu
end if
--Here you would put the statements to execute if the entered date proves to be valid
put "" into tryDate
end if
function invalidDate
global tryDate
convert tryDate to short date
if the result = "invalid date" then
return true
else
return false
end if
end invalidDate
