Convert FileMan files into Caché classes.

Background Information

FileMan is a public-domain set of utilities that provide metadata storage, access, and manipulation for MUMPS applications.

Available Tools

FileMan Wizard

Studio wizard that enables you to quickly and easily create custom classes that represent your FileMan files.

This wizard is also available directly as the %SYSTEM.OBJ.FM2Class class.

See “Migration and Conversion Utilities” in Caché Specialized System Tools and Utilities.

Availability: All namespaces.


The special variable $SYSTEM is bound to the %SYSTEM package. This means that (for ObjectScript) instead of ##class(%SYSTEM.class).method(), you can use $SYSTEM.class.method().
