Real calculator files

The Studio creates tokenized calculator containers—not renamed text files—with the appropriate CE or Evo structure and checksum.

Convert older programs

Import a CE .8xp, inspect its readable source, check Evo compatibility and generate a new .8xp2 when conversion succeeds.

Run and debug

Open the source in a protected browser worker, step through lines, pause at breakpoints and inspect variables in CE or Evo compatibility mode.
