This Read Me document covers changes made since version 2.2.1.
In version 2.2.2, the date format mm/dd/yyyy displayed all the four digits for the year. For example, 25th December, 1991 would be displayed as 12/25/1991. Due to popular demand from our users, in version 2.2.3, we changed this back to to work in the following way :
If the date is from the 20th century, i.e. 19xx, only the last two digits are displayed. For example, 25th December, 1991 is displayed as 12/25/91.
If the date is from any other century, all the four digits are displayed. For example, 25th December, 1891 is displayed as 12/25/1891.
Version 2.2.2 and version 2.2.3
Version 2.2.2 and 2.2.3 offer some routines to compare strings that include all 256 characters in the ASCII table. These routines can be used in the following situations:
• While comparing strings
• While indexing
• While searching
• While sorting
NEW CHARACTERS RECOGNIZED BY 4th DIMENSION
4th DIMENSION now recognizes 17 new characters. These characters are listed below with their ASCII codes. If for some reason, you cannot see all the special characters that are listed below, use TrueType Geneva or open the document with another word processor and set the font for the entire document to Helvetica.
• Å (229) and Á (231) are recognized and attached to the letter A.
• Ê (230), Ë (232), and È (233) are recognized and attached to the letter E.
• î (148), Í (234), Î (235), Ï (236), and Ì (237) are recognized and attached to the letter I.
• º (188), Ò (238), Ô (239), and Ó (241) are recognized and attached to the letter O.
• Ú (242), Û (243), and Ù (244) are recognized and attached to the letter U.
• Ÿ (217) is recognized and attached to the letter Y.

If you use these characters and want to benefit from the new routines for comparisons, refer to the following section.
NEW FEATURES IN CUSTOMIZER PLUS 1.0.2
There is a new item in the Script Manager dialog called String Comparision. The String Comparison pop-up menu contains the following options:
• System
• Extended Tables
These options change the sorting and searching orders. The System option is the default. If you have problems searching on indexed fields that contain special characters, you should should select the Extended Tables option. In this case you MUST rebuild the indices for all alphanumeric fields.
If you are running 4th DIMENSION in multi-user mode with users using different string comparison methods, you will have problems when searching and sorting on indexed fields.
**MAKE SURE THAT YOU ARE USING THE SAME STRING COMPARISON METHOD ACROSS THE SYSTEM.**
SETTING PARAMETERS WITH CUSTOMIZER PLUS
To set parameters with Customizer Plus:
1. Copy the new version of Customizer Plus to your hard disk from the 4th DIMENSION Program 2 disk.
2. Launch Customizer version 1.0.2.
3. Choose Open from the File menu.
4. Select 4th DIMENSION version 2.2.2 from the dialog box that appears.
4. Double-click the Script icon.
The Script Manager window appears.
5. Click down on the String comparisons pop-up menu and choose Extended tables.
An alert box appears containing the following message: “You are about to change the searching/sorting methods.
If you are sure that you want to change the searching/sorting method, you MUST absolutely re-index all indexed alphanumeric fields in all you databases. If you do not re-index, you will get erronous searching/sorting results.”
6. Accept the message and click the window’s close box to close 4th DIMENSION.
A dialog box appears in which you can confirm that you want to save changes.
7. Click Save.
8. Choose Quit from the File menu to quit Customizer Plus.
RE-INDEXING A DATABASE
There are two methods that you can use to re-index your database. The first is done within 4th DIMENSION, and involves manually unchecking and rechecking the Indexed option for all indexed alphanumeric fields.
1. Open the database in the Design environment.
2. Uncheck and then recheck the Indexed option for all indexed alphanumeric fields.
3. Go to the User environment to rebuild your indices.
The second method uses 4D Tools to re-index a database.
1. Launch the 4D Tools application.
2. Open the database to re-index.
3. Choose Compact from the Utilities menu.
The indices will be rebuilt the next time you open the database.
**VERY IMPORTANT**
If you are using a database that uses the new comparison routines in multi-user mode, you must have 4th DIMENSION version 2.2.2 or 2.2.3 installed on each Macintosh. This version should be customized to use the Extended Tables option.
NOTE TO DEVELOPERS ABOUT CUSTOMIZING CUSTOMIZER PLUS
You can control the way in which users work with Customizer Plus. If you want to allow users to use Customizer Plus, but do not want to give them access to the resources, you can do so using the following method:
1. Open Customizer Plus with ResEdit.
2. Open the SECU resource.
Notice that all items have a “1.” Each item represents one icon that appears in Customizer Plus.
3. Enter a “0” in all items that you do not want the user to see.
