Subject: csv next and previous help

Hey there,

I'm trying to figure out how to work with the sample data below such
that I can take each time there is a C in the third column and update
the previous D to a P.

An ideas?

IM,0000002, ,0,@FRIEDEXT01;IMAGES\00\00;0000002.TIF;2
IM,0000003,D,0,@FRIEDEXT01;IMAGES\00\00;0000003.TIF;2
IM,0000004, ,0,@FRIEDEXT01;IMAGES\00\00;0000004.TIF;2
IM,0000005,C,0,@FRIEDEXT01;IMAGES\00\00;0000005.TIF;2
IM,0000006,D,0,@FRIEDEXT01;IMAGES\00\00;0000006.TIF;2

This should end up like this:

IM,0000001,D,0,@FRIEDEXT01;IMAGES\00\00;0000001.TIF;2
IM,0000002, ,0,@FRIEDEXT01;IMAGES\00\00;0000002.TIF;2
IM,0000003,P,0,@FRIEDEXT01;IMAGES\00\00;0000003.TIF;2
IM,0000004, ,0,@FRIEDEXT01;IMAGES\00\00;0000004.TIF;2
IM,0000005,C,0,@FRIEDEXT01;IMAGES\00\00;0000005.TIF;2
IM,0000006,D,0,@FRIEDEXT01;IMAGES\00\00;0000006.TIF;2

Thank you,
