#[BASIC][1] (QBasic 4.5), <s>10</s> <s>5</s> 3 bytes

*In the BASIC programming language, RUN is used to start program execution from direct mode, or to start a overlay program from a loader program.* - [Wikipedia](https://en.wikipedia.org/wiki/Run_command)

Edit: This works without a line number in QBasic 4.5, according to @steenbergh

	RUN

Here's the first version I posted. Infinite GOTO loop. Also, it's 10 bytes, which is a nice coincidence!

	10 GOTO 10
