EXIT closes the entire script

Software EleganceCode Complexity

Why you should care

EXIT instruction is designed to exit the entire script hence the purpose of having only one instruction at a time. EXIT instruction has the capability of causing some of the script to be unread if placed incorrectly. As a result, the script will have compilation errors.

Business Impacts

EXIT is an instruction that can add complexity if not used properly which results in a loss of time that could be used towards innovating the script instead.
