Code

property Code: string read write;

Example

procedure ScriptEvent(var Value: Variant);
begin
  Value := Locals['BatchReference'].Code;
end;

Usage

Code gets or sets the variable identifier, with an intentionally unlocked getter and no automatic dataset rename.

Additional Technical Info

Code is the mutable string identifier used by variable lists/groups and as the initial DataSetName for lazy Data.

The setter uses the per-variable monitor. The getter deliberately returns FCode without locking, based on a source assumption that callers enumerate under an owning-list lock. Script reads are not guaranteed to satisfy that assumption, so a concurrent Code write is a data race.

Changing Code does not re-key/reorder an owning list and can create duplicate or unfindable entries depending on that owner's lookup logic. It also does not rename an already-created dataset; DataSetName snapshots Code only at first Data access.

Do not casually rename list/group-owned variables. Use owner configuration/lifecycle operations where available, and treat Code plus Value reads as separate non-atomic snapshots.
