Macros in Excel are written in a language called VBA. Like other programming languages, VBA includes certain programming structures that are used to control how the program executes. One of these structures is the While...Wend structure. This structure has the following syntax:
While condition program statements Wend
When a macro is executing and this structure is encountered, the language tests whatever condition you have defined. You can see examples of conditions in many of the macros used in ExcelTips. If the condition is true, then the program statements between the While and Wend keywords are executed. If the condition is not true, execution of the macro continues with the statement following the Wend keyword. If the conditions are true when Wend is encountered, the macro will loop back up to the While statement and keep executing the loop until the condition becomes false.
