Trying To Search A Line of Text To Variables

Ok Here Is What I have got so far I need to get a line of text from a file and use the data for variables in the program. The text is on multiple lines and looks like this.

S1 2 3 5 5
S2 1 3 4 8
S3 1 2 3 4

I need the program to search the file and extract the data if it exists if not ask the user to search again for another file. I need after the game is finished to delete the savegame file. When asking to save I need the program to search to make sure that the line does not already exist. This is my program so far. I need some help accomplishing this thank you.
