# Cataloging a FlashBASIC Module

Cataloging makes code easier to locate. It is not necessary
to catalog a BASIC module to run or call it. Cataloging does not affect
performance since the object code is always loaded in a dynamically
extensible shared memory segment.

There are two catalogs: the account and the domain catalogs.

## Account Catalog

The Account Catalog is created
with the TCL catalog command. A record is added
to the Master Dictionary of the account the user is logged to. The
Account Catalog is available only to VME, ODBC, PickDP and FlashCONNECT
applications.

To catalog a Flash module after compiling it,
type:

```
catalog bp module
```

## Domain Catalog

**For UNIX:** Not Supported

The Domain Catalog describes domain-wise elements. The RuleModules
domain catalog allows a distributed application to locate BASIC subroutines
called by VB Rule Module objects or from the File Manager.

The
Domain Catalog can be updated from TCL or the D3 File Manager.

- To update from TCL: Run the TCL catalog command with the (g option. ```
catalog bp module (g
```

- To update from the D3 File Manager: Right-click the modules, then select Flash Catalog.Note: Routines that are called from Visual Basic modules or triggers should be in the Domain Catalog. This avoids having to specify an explicit path when calling modules.Warning: The key to the Domain Catalog is the name of the module. Only 1 module of the same name can be in the Domain Catalog.
