Hello world

Here’s the shortest useful Mantis script. It sets a human-like typing pace and types a greeting:

REM My first Mantis script
SET_SPEED $Human
STRINGLN Hello from Mantis!

1REM My first Mantis script
2SET_SPEED $Human
3STRINGLN Hello from Mantis!

Line by line:

• REM — a comment. The compiler ignores everything after it on that line.
• SET_SPEED $Human — paces every keystroke that follows so it looks like natural typing rather than an instant paste.
• STRINGLN Hello from Mantis! — types the text exactly as written, then presses Enter.

Save the file, hit Compile (Ctrl+B) in Karvi Studio, pick your device’s COM port, and hit Upload (Ctrl+U). Plug Mantis in without holding the Upload button, and it types the line above on whatever has focus.
