## Triggers

OnRun

## Calls

From the extracted call graph of BC29 (graphify-al on the snapshot checkout): calls whose target is known from a declared type or an `Object::"Name"` argument. Interface dispatch and calls through events are not counted, so the list is not complete.

- [Codeunit 3000 "DotNet_Array"](../codeunit/3000.md) (6 calls: `FromCharArray → GetArray`, `Split → GetArray`, `Split → SetArray`, …)
- [Codeunit 3008 "DotNet_NormalizationForm"](../codeunit/3008.md) (2 calls: `IsNormalized → GetNormalizationForm`, `Normalize → GetNormalizationForm`)

## Called by

- [Codeunit 1249 "Transform. Rule - Replace"](../codeunit/1249.md) (2 calls: `StringReplace → Replace`, `StringReplace → Set`)
- [Codeunit 20132 "Script Data Type Mgmt."](../codeunit/20132.md) (2 calls: `Trim → Set`, `Trim → Trim`)

## Across versions

- Present in: BC23-30
- Changed (declaration) in: BC28

Source: AL metadata extracted from the code (names, ids, signatures, properties); no code bodies (D10).

## Ask your agent

Procedure bodies are not stored here (D10). The call sections above are our own, per object, from the BC29 call graph. For a procedure body or the calls of one procedure, ask bc-code-atlas (external, by Stefan Maron, MIT; default corpus w1-28), which the bc-observatory plugin connects: `bcatlas_resolve_node(object_type: "codeunit", object_name: "DotNet_String")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
