WD97: Numbers Containing Hyphens Sort Incorrectly (196758)


The information in this article applies to:

  • Microsoft Word 97 for Windows
This article was previously published under Q196758

SYMPTOMS

In some cases, Word may sort numbers incorrectly.

Case 1

When you perform a numeric sort operation on numbers that contain hyphens, such as social security numbers, phone numbers, and nine-digit ZIP Codes (postal codes), Word may sort the numbers incorrectly.

Case 2

Similarly, Word may sort your mail merge data incorrectly when you sort mail merge data records by using the Sort Records tab in the Query Options dialog box.

CAUSE

Case 1

If you select Number for the Sort By Type setting in the Table Sort Numbers dialog box, Word treats the hyphen as a minus sign. As a result, Word performs a subtraction operation and then sorts the difference. For example, if you sort the following list of nine-digit postal codes, Word performs a subtraction operation and then sorts the result. 

   Nine-Digit Postal Code            Result If Subtracted
   ------------------------------------------------------

   11111-1111                        10000
   99999-9999                        90000
   95000-0001                        94999
   98000-9999                        88001

   Result of Sorting as Number       Number Used for Sorting
   ---------------------------------------------------------

   11111-1111                        10000
   98000-9999                        88001
   99999-9999                        90000
   95000-0001                        94999

Case 2

Similarly, in a mail merge operation, if you perform a sorting operation based on a field that contains hyphenated numeric data, Word automatically treats your data as numeric and, therefore, uses the hyphen as a minus sign. (To sort from a mail merge operation, open the Mail Merge Helper and then click Query Options.)

NOTE: Word treats the data in any mail merge field as numeric if the first character in the field is a number.

WORKAROUND

Method 1: Sort as Text

To correctly sort numbers that contain hyphens, select Text as the Sort By Type setting in the Table Sort Numbers dialog box.

Method 2: Sort Data File Before Merging

For a mail merge operation, if you want to sort based on a field that contains hyphenated numbers, sort the data source before you perform the mail merge operation instead of using the Mail Merge Helper.

Method 3: Replace Hyphens Before You Sort the Data

If you want to sort hyphenated data and use the Number (Numeric) Type setting, follow these steps:
  1. Before you perform the sorting operation, replace the hyphens with periods (.).
  2. Sort the data using the Mail Merge Helper or the Sort Text command on the Table menu.
  3. Replace the periods with hyphens to restore your original numeric data.
