Joseph Doherty 32f26272ae Initial commit: Wonderware / System Platform tools and reference
Five tools under one repo, all docs organized per DOCS-GUIDE.md:

- aalogcli: .NET 4.8 / x86 CliFx CLI for reading System Platform binary
  logs (*.aaLGX) for LLM debugging, built on aaOpenSource/aaLog. Commands:
  last, tail, range, unread, fields. Stable JSON envelope under --llm-json.
  Build template under lib/build/ for rebuilding aaLogReader.dll.

- aot: ArchestrA Object Toolkit 2014 v4.0 reference material. Dev guide
  (Markdown converted from CHM), API reference for the ArchestrA.Toolkit
  namespace, and the Monitor / Watchdog VS sample solutions.

- graccesscli: .NET 4.8 / x86 CliFx CLI that automates Galaxy
  configuration via the ArchestrA GRAccess COM interop. Includes session
  daemon, IPC protocol, and llm-json envelope contract.

- grdb: SQL/DDL exploration of the Galaxy Repository database. DDL
  captures, reusable queries, hierarchy / contained-name <-> tag-name
  translation notes.

- histdb: LLM-oriented reference for AVEVA Historian retrieval. INSQL
  linked-server, extension tables, every wwXxx time-domain extension,
  every retrieval mode, alarm/event SQL recipes, REST API. Distilled
  from the 243-page Historian Retrieval Guide.

Root contains:
- CLAUDE.md: thin index pointing into each tool's README.
- DOCS-GUIDE.md: doctrine for organizing docs for LLM consumption.

Allows a user to set the value of the referenced attribute.
**Syntax**
```csharp
public CMxValue Value { set; }
```
**Returns**
CMxValue
## CMxIndirectWriteOnly Constructor
### CMxIndirectWriteOnly Constructor string, string, IMxSupervisoryConnection3, RuntimeBase, int, short, int
This is an internal constructor intended for use only in BindToWriteOnly.

```csharp
CMxIndirectWriteOnly(string _fullRefString, string _context, IMxSupervisoryConnection3 _superConn, RuntimeBase _rb, int _refHandle, short _statusId, int _statusIndex)
```
**Parameters**
**`_fullRefString`**
[in] Full reference string of the attribute to bind to.
**`_context`**
[in] Context of the reference.
**`_superConn`**
[in] A supervisory connection to the runtime.
**`_rb`**
