>>>How do I clear a date field and a datetime field

>>Mechanically, you can do it like this if it's in a table or cursor:
>>

SCATTER NAME xyz BLANK
>>REPLACE dDate     WITH xyz.dDate
>>REPLACE tDateTime WITH xyz.tDateTime
>>RELEASE xyz

>>
>>Or you can use the blank forms directly:
>>

thisForm.myDateControl.Value     = CTOD("  /  /    ")
>>thisForm.myDatetimeControl.Value = CTOT("  /  /     :  :   AM")
>>REPLACE dDate     WITH CTOD("  /  /    ")
>>REPLACE tDateTime WITH CTOT("  /  /     :  :   AM")

>>
>>You can also use the BLANK command if it's in a table:
>>

BLANK dDate, tDateTime

>>
>>And if you need it set back to NULL, you can use:
>>

REPLACE dDate     WITH {  /  /  }
>>REPLACE tDateTime WITH {  /  /     :  :   AM}
