Title: [Error] Trouble with "while condition do"

Hello, the following program results in the error "bios:338: [string "startup"]:5: 'do' expected" and i'm unable to fix it. Changing line 5 to "while 1=1 do" still yielded the same error message. Any ideas why?

edit: Finally figured this out, it needed to be "==" instead of "=". But I still have no idea why, shouldn't "integer=integer" be true or false?

When you are comparing two variables, then you need to use the '==' operation. When you are assigning a new variable, you use the '=' operation.
