Most of the corpus — FindSet/SetLoadFields/CalcFields patterns, permission sets, SingleInstance codeunits, DataClassification, IsolatedStorage, transaction scope, SecretText — describes BC platform behaviour that is identical across supported versions. The seed [26..28] range on every file implied a version-specificity the content does not actually have, and there was no way to express "applies to every version" in the schema the way [w1] and [all] already do for countries and application-area. Extend the v1 schema with a universal sentinel for bc-version, parallel to the sentinels already defined for the other dimensions: bc-version: [all] # applies to every BC version [all] is mutually exclusive with explicit versions. Range shorthand ([26..28]) and explicit lists ([26, 27, 28]) continue to work for files genuinely tied to a version-gated API or deprecation. Update read.md (field definition, matching semantics, partial-context rule), write.md (default to [all], use ranges only with a concrete reason), README.md (frontmatter example), and the CI validator. All forty existing knowledge files and the three action skills convert to [all]; none of the current content is version-gated. Validator passes.

# Do not pair FindFirst, FindLast, or Get with Next
|
|
|
|
## Description
|
|
|
|
CodeCop rule AA0233 flags loops that start with FindFirst, FindLast, or Get and then call Next. FindFirst and FindLast retrieve a single row and reposition the cursor; calling Next after them forces the platform to re-seek and stream the rest of the set, which is slower than the correct FindSet pattern and signals intent incorrectly to reviewers and the optimizer.
|
|
|
|
## Best Practice
|
|
|
|
Choose the Find variant that matches the operation: FindSet for full iteration, FindFirst or FindLast when you want exactly one row, Get when the primary key is known. Never call Next after FindFirst, FindLast, or Get.
|
|
|
|
## Anti Pattern
|
|
|
|
Writing `if Rec.FindFirst() then repeat ... until Rec.Next() = 0` is the canonical AA0233 offender. The loop wastes bandwidth and obscures the author's intent.

See sample: `avoid-findfirst-with-next.bad.al`.
