I'm using text files as an array to store and remove information, however I do not know know how to adapt this code so the line I search for is removed.
My text files are set up as such:

062,Fredrikson,6 Freil Road,Gravesend,CT9 1RB,12/06/1995,13 March 2012,Silver
So I can search and locate the ID, in these cases 021 or 062, but I want to be able to remove the line I want, once it's been found.
