Intf_

Intf_ = 18

Example​

procedure ScriptEvent(var Value: variant);
begin
  // Do not use Intf_; select the named interface required by the flow.
  Value := Intf_Order;
end;

Usage​

Intf_ records an unsupported Code Library collision created by six blank reserved interface registrations and explains why scripts must not use it.

Additional Technical Info​

Do not use Intf_ in scripts or configuration.

Intf_ is not a supported Velox interface identifier. The page exists because the scripting importer registers the same incomplete name six times for reserved database slots 14-19, and the Code Library index collapsed those duplicate registrations into one generated record.

The current _Index.json declaration displays Intf_ = 18. That value is a generator/index collision artefact, not a stable public contract for reserved interface 18.

Generated declaration​

This declaration reports the current Code Library snapshot only. It must not be used as proof of the effective runtime value.

Implementation​

The fresh-build Interface table reserves rows 14, 15, 16, 17, 18 and 19. Every row has a blank Code, is not a module, is not configured and is inactive.

vxVeloxEDI.pas deliberately declares no native Intf_ constant. However, uPSI_vxVeloxEDI.pas contains six registrations with the identical name Intf_ and values 14 through 19, plus six duplicate blank-code registrations named Intf__String.

The current Code Library index retained one numeric record and reports value 18. It did not produce an Intf__String.md page. InitVeloxConstMap has no Intf_ entry.

Behaviour​

No reliable supported behaviour is defined for this name. Scripts should select a complete named constant such as Intf_Order, Intf_ASN or Intf_Partner.

The six database rows are placeholders. Their blank codes and inactive flags do not assign them a shared interface meaning.

Edge cases and quirks​

  • Duplicate compile-time registrations mean the Code Library record cannot identify which definition, if any, a particular script compiler lookup will resolve. The documentation does not infer runtime duplicate-name behavior from the index snapshot.
  • The displayed value 18 is neither the first registration (14) nor the last registration (19), reinforcing that it is not a canonical reserved value.
  • <!Intf_!> is not a valid Velox numeric tag because the name is absent from gVeloxConstMap; tag processing raises an invalid-tag exception.
  • There is no supported String partner. Do not construct or use Intf__String.
  • Do not use numeric literals 14-19 as substitute interface identifiers. They remain reserved database keys without public module/reference semantics.
  • Future generator or importer correction may remove or change this page. That is expected and should not be treated as a compatibility break for supported scripts.

Side effects​

Reading a compile-time name has no intrinsic side effect, but relying on this collision can select an unintended value and direct later database work at a reserved row.

Errors​

Compilation or evaluation may vary with duplicate-registration handling. Configuration tag expansion always rejects Intf_ in the current product. Database consumers can also fail or behave incorrectly because rows 14-19 have blank codes and no configured interface role.

Performance and concurrency​

No meaningful performance contract applies. The reserved rows are mutable database state, while the conflicting registrations are fixed in the deployed executable.

Remarks​

This page documents a known product/importer defect so technical users and AI agents do not mistake generated visibility for supported API status. Use only complete named interface entries documented in this folder.

  • Intf_Order — supported module identifier example.
  • Intf_ASN — supported module identifier with its paired String code.
  • ProcessTags — rejects names absent from the numeric Velox tag map.

External references​

No Delphi or Free Pascal equivalent applies. This collision is specific to the Velox importer and Code Library generator.
