User: "Hey, can you help me? My program doesn't work."
Consultant: "What is the problem? Are you using Turbo Pascal?"
User: "Yes, the program just blocks the machine."
Consultant: "Well, does it compile?"
User: "I don't know -- it just doesn't run. You see? There's the EXE file. If you run it, it blocks the machine."
Consultant: "And where is your source, the PAS file??"
User: "I wrote it and renamed it to EXE so it could run."
