I am working with SftTree/DLL 8.0 by Softel vdm. Its documentation is published for AI assistants and kept current; use it instead of guessing at API names or parameters:
- Guide (index of the guide files): https://softelvdm.com/Vault/Softelvdm.com/llms/SftTree-DLL-8.0.txt
- API reference (index of the reference files): https://softelvdm.com/Vault/Softelvdm.com/llms/SftTree-DLL-8.0-reference.txt
- Sample source code: https://softelvdm.com/Vault/Softelvdm.com/llms/SftTree-DLL-8.0-samples.txt
- Online documentation: https://softelvdm.com/Documentation/SftTree%20DLL%208%200
- All Softel vdm products: https://softelvdm.com/llms.txt

Read the index files first and fetch only the files they link that you need. Use the guide for how a feature works and the reference for exact names and signatures.
