Is there a way to start at a specified line, like a goto statement?

In this article, you will learn about how to use goto statement in Golang. Goto statement is found in many programming languages. It is altered the normal sequence of program execution by transferring control to some other part of the program. The goto statement is also known as the unconditional jump statement.
Syntax of goto Statementgoto label; ... .. ... ... .. ... label: statement; The label is an identifier. When the goto statement is encountered, the control of the program jumps to label: and starts executing the code.
A goto statement causes your program to unconditionally transfer control to the statement that is associated with the label specified on the goto statement.
The goto statement can be used to alter the flow of control in a program. Although the goto statement can be used to create loops with finite repetition times, use of other loop structures such as for, while, and do while is recommended.
First, it would be statement, not a command. Second, see ruby-goto. Third, note

There is the ruby command line switch -x.
-x[directory] Tells Ruby that the script is embedded in a message.
Leading garbage will be discarded until the first that
starts with “#!” and contains the string, “ruby”. Any
meaningful switches on that line will applied. The end of
script must be specified with either EOF, ^D (control-D),
^Z (control-Z), or reserved word __END__. If the direc‐
tory name is specified, Ruby will switch to that directory
before executing script.
BTW, I'm pretty sure ruby-goto was, umm, a joke. I don't believe the download link has ever worked. Or am I just supposed to point people to it and keep quiet? I never know...
I liked Ryan's next line after announcing ruby-goto:
Stay tuned for the next evil module... ruby-malloc! Have a nice day.
Ryan is clearly a genius.
