I need a procedure written in TP 5.5 that will save the entire screen or a portion to a file. I have been unsuccessful in writing my own so any help would be greatly appreciated.

If you want to do parts of the screen, you will have to loop through by scanline. Remember that the video memory is interlaced for CGA graphics - you have to add 16K*odd(scanline). I also recommend Ohlsen and Stoker, but you might want to code this without having to go out and search for a book.
