# Subprograms

Any program in TRIK Studio can be saved as a subprogram and used in another program.

Subprograms [can be saved](#save) to a local collection or [exported](#export) to a separate file for transfer to other computers.

To work with the collection of subprograms, use the menu item `Tools → Subprograms`:

1. [Export to file](#export).
2. [Import from file](#import).
3. [Save to collection](#save).
4. [Load from the collection](#load).
5. [Clear collection](#delete).
