Is there a way within a KSH to exit a case statement and go to a certain line for next execution with the code? Or are there goto labels you can use? Anything like this used instead of nesting tons of branching?
There are no labels or goto. However, you can exit a deeply-nested loop by passing a number to the "break" builtin: break 2 to exit two levels, break 3 to exit three levels, etc.
