• the program was using invisible pop-up windows as temporary data buffers to implement wizard-like operations in the user-interface, and never deallocating them.
• every variable was global
• there were no data structures anywhere for anything
• there were no functions other than those required by the GUI
• several functions were over 75 pages long - that's about 4500 lines of code in a single function
• the level of code redundancy was incredible; it was common to see the same 5-10 lines of code repeated several dozen times within the same function
