# op\_enum

Convert operand to a symbolic constant (for the explanations of 'ea' and 'n' please see [op\_bin](/8.4/developer-guide/idc/idc-api-reference/alphabetical-list-of-idc-functions/696.md)()) enumid - id of enumeration type serial - serial number of the constant in the enumeration The serial numbers are used if there are more than one symbolic constant with the same value in the enumeration. In this case the first defined constant get the serial number 0, then second 1, etc. There could be 256 symbolic constants with the same value in the enumeration.

success op\_enum(long ea, int n, long enumid, long serial);

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.hex-rays.com/8.4/developer-guide/idc/idc-api-reference/alphabetical-list-of-idc-functions/704.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
