Scratch 0.1, created on February 14, 2004, was the first version of Scratch. It was not released to the public until much after its creation.


As Scratch 0.1 was the first release of Scratch, all features are new. Scratch 0.1 had seven categories: control, math, mouse/keyboard, motion, sensing, variables, and scripts. Scratch 0.1 contained a total of 43 blocks.


Unlike newer versions of Scratch that used reporter stage monitors, Scratch 0.1 simply provided pre-defined variables. The variables "x", "y", "layer", "heading", "width", "height", "xScale", "yScale", "transparency", and "penSize" were created by default and could not be deleted, holding values defined by the blocks associated with them. Additional variables could still be created and deleted manually.

Procedures in Scratch 0.1

Main article: Scripts (category)

Procedures, or "scripts" as they are called in the Scratch 0.1 editor, are Scratch 0.1's equivalent of "My Blocks" in Scratch 2.0 and 3.0. Procedures in Scratch 0.1 can be renamed, input parameters can be added, and buttons can even be created for them. Such procedures also make use of the "answer []" block, which returns the value specified in the input. These procedures can be used as reporters or be run independently, and they can even check if other procedures are running. Procedures can also be started and stopped individually. To access these options in Scratch 0.1, one must right-click a hat block.

Note Note: "Scripts" in this section are not the same as the collections of attached blocks called scripts. For information about those, see Scripts.
