I have some processing of records to do & I'm thinking like a DOS programmer. Please help me think like a VFP programmer.

I have a table on a floppy disk named people. I have a table in my project called people (which I've given an alias of peo). I want to read through the table on drive a, check to see if it's in people & replace certain fields if it is or add the record it it's not.

In DOS, I said
select 1
use a:people
sele 2
use people alias peo
set order to dnumber
sele 1
do while not eof()
sele 2
seek people.dnumber
if found()
replace ...
else
appe blank
replace ...
endif
select 1
skip
enddo

How do I do this in VFP?

Many, many thanks for your help.
