For devotees of Jackson Structured programming, the GOTO is a must for POSIT and ADMIT processing. Otherwise it can be messy avoiding a GOTO.
The problem with GOTO is that the suitability of the target branch location is not enforced by the compiler according to any structured discipline.
Premature terminations (posit/quit/admit) can almost always be handled with LEAVE-type statements or immediate return from a subroutine. Some languages have SIGNAL, EXIT, etc. which can help provide structured premature termination for larger routines without resorting to the dreaded GOTO.
