Old programs do not run

[BuSchu]

After a long time, I wanted to start my few programs again. But none of them can still run. When I look at the program text and select "check", I only get the error message "Error: Syntaxerror". And that with every program. Then when I press ESC twice, I always get the message that there is a syntax error on line 6.
Here is my simplest test program:

EXPORT Testinput()
BEGIN
LOCAL name;

INPUT ({{name, [-1]}}, "Name", "Please type in a name");
PRINT("Hello " + name);
END;

Why am I getting a syntax error with this tiny program now?

Thank you for your help!
