Required Entry

[Michael Lee]

What Frank has here is perfect for entry mode, but if the situation is as Bob
Deskin suggests then you will get this message everytime you are in that
field-even if there is data already in the field.

If the situation is that the user finds data and then modifies it and you want
to force entry in any blank EXISTING field data you might want to modify Frank's
code slightly as follows:

Procedure Input Field1
Begin
       If 0=size(fieldtext) and oldvalue(field1) = ' '    ; <-- or NULL, but I'm
not sure

;      of the syntax...
       then error 'Field1 is a required field'
End
