Any kind of branching statement can be considered as, and implemented as, a limited goto. Which doesn't mean they're all the same thing.

Ahhh, but the concept of GOTO a line number and/or label is alien to the shell.

Joke code that works, ;o)
(Note the smiley.)
Code:
#!/bin/sh
# goto
goto() { eval $1 ; }
label1() { echo "Test line 1." ; }
label2() { echo "Test line 2." ; }
label3() { echo "Test line 3." ; }
goto label1
goto label2
goto label3
goto label1
goto label2
goto label3

I know, I know, it is dreadful coding...
Results in CygWin:-
Code:
AMIGA:~> goto.sh
Test line 1.
Test line 2.
Test line 3.
Test line 1.
Test line 2.
Test line 3.
AMIGA:~> _

I tend to stay away from functions unless they will be called more than once. I have the misfortune of trying to clean up after people who were "function happy" to the point that there are more functions than lines calling them with the called only running once.
