  3. Look for (princ lines immediately after—these often tell you what the command does.

Cons & Risks (Important!)

| Risk | Explanation | |------|-------------| | Malware | Rare but possible – some .lsp files contain hidden (startapp) or (vl-file-delete) calls. Always scan or audit before loading. | | Outdated commands | Uses command without error trapping → can crash your session. | | No undo tracking | Many older LISPs don’t wrap actions in (command "_.undo" "_BE") / _E. One wrong click = lost work. | | Naming conflicts | A routine may override a built-in command (e.g., a poorly written DD.lsp breaking DD for direct distance). | | No documentation | You get hundreds of files with no guide on what each does or its syntax. |
