Snarled program logic is unstructured logic, also known as "spaghetti" logic. Compiled machine code is the ultimate example of snarled program logic. Although spaghetti code is more compact and efficient than structured code, it is extremely difficult to both comprehend and maintain. Hence we use structured programming languages to provide a high level of abstraction between the logic of the programmer and the snarled logic of the machine-dependant code.

gli spaghetti - the spaghetti

Firefighters refer to spaghetti the same as you do, Spaghetti is Spaghetti.

The go-to-statements has been the source of Spaghetti code since early software development eras. The go-to-statements provide an easy way to "jump" to the right place to execute some code, and then jump to another block...

When two "path" (the noodle) cross each other (on drawing board of course), or more, the graph would look like a plate of spaghetti....

That "make-you-hungy" graph can be done in most of the programming languages. It is a thing to be avoided in your code!

Because the use of GOTO creates code that jumps all over the place, and is hard to read and follow, often referred to as "spaghetti code".
