Order_Line_Same

Order_Line_Same = 2

Example​

procedure ScriptEvent(var Value: variant);
begin
  Value := GetOrderLineStatusCode(Order_Line_Same); // 'Same'
end;

Usage​

Order_Line_Same identifies the Same order-line comparison state as Order_Line_Status.Num value 2 for Velox scripts and mappings.

Additional Technical Info​

Order_Line_Same is the script-visible LongInt identifier for the Same order-line comparison state. Its fixed value is 2, paired with Order_Line_Same_String. It describes a comparison outcome and does not prove that every business field is identical outside the owning process.

Implementation

Velox declares and registers the fixed LongInt value 2. GetOrderLineStatusCode maps it to Same; GetOrderLineStatusNum performs the reverse mapping. The numeric name is registered in the Velox tag map, so <!Order_Line_Same!> expands to 2.

A fresh VxData database seeds Order_Line_Status row 2 with description Same, and Order_Line.StatusNum references that domain.

Behaviour

Use Order_Line_Same only in the order-line comparison state domain. The fixed reverse converter recognises the canonical token without querying the database. Reading or comparing the constant does not assign Order_Line.StatusNum or run order processing.

Edge cases and quirks

  • PascalScript stores the value as an untyped integer for domain purposes. 2 also occurs in other order families and can have a different meaning there.
  • Line and response value 3 both use text Changed, but they belong to different database tables, fields and converters.
  • Response value 2 is Rejected, while line value 2 is Same; the identical number is not semantically interchangeable.
  • Number-to-text conversion returns Null for Null or an unsupported value rather than choosing a default.

Side effects

Reading Order_Line_Same, expanding its tag or comparing it has no I/O or state-changing side effect. Any persistence or processing effect comes from the caller.

Errors

Reading the constant does not raise an error. Passing a value from another numeric domain can silently select the wrong branch before a database constraint or later business rule detects it.

Performance and concurrency

This is an immutable compiled value. Access and fixed-case conversion are constant-time for practical purposes and carry no shared mutable state.

Remarks

The example is source-reviewed and non-destructive. It performs only fixed numeric-to-text conversion.
