# 0089: Opcode not found The compiler found a command that is not available with vanilla game and the [extensions](/edit-modes/extensions.md) used in this script. **Possible solutions:** add a [directive](/language/directives.md#usduse) `{$USE }` where `` is one of the [available extensions](/edit-modes/extensions.md#extensions-list) defining this command. For example, opcode `0BA2` in GTA III is only available with CLEO 2.0 and MemoryModule plugin. In order to make you aware of this extra dependency the compiler throws this error if it can't find `{$USE memory}`. For existing scripts adding this directive will be a one-time change to let it compile again. ``` {$USE memory} ``` If you're unsure which extension the command belongs to, go to [Sanny Builder Library](https://library.sannybuilder.com/) and find it there. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
