Right now I want to keep it for myself. I might make it public later. If you want to know how a specific part/function works I might help you out. The main functions (BIC/SAV Input/Output, calls to Common dialogs) are about 2800 lines (comments included (might be 2500 lines without (just guessing))) The Functions for PCX graphics stay at 230 lines My file with constants, types (structures) and variables is 580 lines. (Yes I decided to move them to their own file to get some overview over them and the functions, but some types (40 lines) are still in the PCX-function file) I have 120 lines for the file with System Functions, types and constants.
