Just to mention another option:

= --(COUNTBLANK(A1:C1)=0)

One difference with this vs using COUNTA is that
COUNTA will count a cell with a Prefix Character (ie ') has having data, and
CountBlank will not.

One way (assumes we're working in row 2)
=IF(AND(LEN(A2)0,LEN(B2)0,LEN(C2)0),1,0)

I have 3 columns with misc data. Column A is a date, column B is an
invoice number and C is an expense report number. If all 3 columns
have data entered, I would like to have a formula return the number
"1" if not, "0"

How do I do this?
