# Subprograms

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

Subprograms [can be saved](/en/studio/programming-visual/subprograms.md#save) to a local collection or [exported](/en/studio/programming-visual/subprograms.md#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](/en/studio/programming-visual/subprograms.md#export).
2. [Import from file](/en/studio/programming-visual/subprograms.md#import).
3. [Save to collection](/en/studio/programming-visual/subprograms.md#save).
4. [Load from the collection](/en/studio/programming-visual/subprograms.md#load).
5. [Clear collection](/en/studio/programming-visual/subprograms.md#delete).
