Architecture Evolution

v3.60 Philosophy

  • Commercial Product: Registration enforced, trial period, license manager

  • Modular VLX: 109 separate FAS modules for selective loading

  • Protected Code: All modules compiled and encrypted

  • User-Friendly: System variable preservation, error recovery

  • Batch Files: Trial period tracking via cv.bat date stamp

v7.0 Philosophy

  • Internal/Patch Version: No registration, free to use

  • Monolithic Core: Single CSV.FAS + auto-loaded plain LSP

  • Hybrid Protection: Core protected, modules open

  • Developer-Focused: Hardcoded settings, no preservation

  • Simplified: Batch files without trial tracking
