I have a spreadsheet in which A:1 contains First and Second Names as a
single entry, e.g. 'Fred Smith'.

I want to be able to include only the First Name in statements in other
fields, e.g. 'Fred can .' I have considered splitting the name across two
fields, but this would introduce other complications.

How can I refer to A:1 such that only the first name, which is of variable
length, will be picked up, i.e. everything up to, and possibly including'
the space?

I know I can use '=A:1& 'can.'' which will come out as 'Fred Smith can.',
but how do I make it read 'Fred can.'?
