From the Format Browser, select the Change command from the Formats menu to edit an existing format. As you edit your format, an example of that format is displayed at the bottom of the dialog.
To edit a format
In the Format Browser, select the format that you want to edit.
Select the Change command from the Formats menu.
The Edit Format dialog for the type of format that you selected is then displayed, to enable you to amend your defined values to meet your requirements. For example, if you selected a short date format called MyShortDateFormat from the Format Browser, the Edit Short Date Format dialog is then displayed.
The values that you defined for that format are then displayed in the appropriate combo boxes, text boxes, or option buttons.
Amend the displayed values, as required.
You can change any value other than the format name. If you want to alter the name of an existing format, you must add a new format with the appropriate name and values, and then delete the wrongly named format, if appropriate.
Click the OK button. Alternatively, click the Cancel button to abandon your selection.
The Format Browser is then redisplayed. The format that you edited is highlighted and an example of the amended format is then displayed in the status line.
