What the specification says
Note that the name of this field is changing to "OrderCapacity" as Rule80A is a very US market-specific term. Other world markets need to convey similar information, however, often a subset of the US values. . See the "Rule80A (aka OrderCapacity) Usage by Market" appendix for market-specific usage of this field.

Shown with | separators for readability. On the wire FIX uses SOH (0x01), an invisible control byte — and because BodyLength and CheckSum are computed over the actual bytes, the two forms have different checksums. Both are valid and both decode here.
Generated from the FIX 4.2 dictionary and verified at build time: it parses and validates with no issues. Open the decoder to try your own message.
Valid values
A value outside this list is not a parse error — the message still decodes — but validate() reports it as validate/value-not-in-enum.

Where tag 47 appears
Requiredness is a property of the message, not of the field: the same tag can be optional in one message and conditionally required in another.
| Message | MsgType | Requiredness | Where in the message |
|---|---|---|---|
| ExecutionReport | 8 | Optional | directly on the message body |
| OrderCancelReplaceRequest | G | Optional | directly on the message body |
| OrderList | E | Optional | directly on the message body |
| OrderSingle | D | Optional | directly on the message body |
Wire format
A single character. Most char fields are enumerated, so the value is one of a fixed set rather than arbitrary text. @boarteam/fix keeps the value as a string and, for enumerated fields, reports validate/value-not-in-enum when it is not a defined value.
Read tag 47 in TypeScript
import { createFixEngine } from "@boarteam/fix";import { dictionary } from "@boarteam/fix-dict-fix42";const fix = createFixEngine(dictionary);const { message, issues } = fix.parse(raw);const rule80A = message.fields[47]?.raw;// e.g. "A" — Agency single order// The dictionary also carries the labels:const label = fix.dictionary .fieldByTag(47) ?.enumValues?.find((e) => e.value === rule80A) ?.description;Other char fields
Decode this in your own code
The same engine that produced the decoded example above is an Apache-2.0 npm package with zero runtime dependencies. It runs in Node and in the browser, and parse() returns problems as data instead of throwing.
npm i @boarteam/fix @boarteam/fix-dict-fix42
