What problem does it solve? Divalto ERP stores configuration data (zooms, menus, multichoix dictionaries) in proprietary indexed binary .dhfi files that cannot be inspected with standard tools. This Skill lets you query those files directly from Python to audit, debug, or verify ERP configuration without opening the Divalto client. ## Core Features & Use Cases - Keyed and sequential reading: Read records by index key (e.g. A4 for zooms, A2 for menus), position on a specific key value, or scan sequentially forward and in reverse. - Filtering and projection: Apply cumulative Champ=Valeur filters and return only selected fields, with results emitted as structured JSON. - Pre-built record structures: Ships validated JSON structure definitions for A5F zoom tables (M4, M1), Xmenuf menu tables (M2, M0), and the gtfdmc multichoix dictionary, plus a structure validator. - Use Case: You need to find which zoom record has ZoomNum=9490 in a5f.dhfi and see only its label and target file. Run read_isam.py with the M4 structure, key A4, a ZoomNum filter, and a field projection to get the answer as JSON in one command. ## Quick Start Ask the assistant to read the first five zoom records from a5f.dhfi using the M4 structure on key A4 and show the result as JSON.
