The fortran output from plusforts spag will be numerically identical to the input.
It goes without saying that this code is mainly just for entertainment purposes, since using goto is considered lazy programming and is a debugging nightmare. I used a lot the goto and label functions with casio graphic calculators when i was in high school, with matlab you dont need to use the goto function, if theres a part of the code that is used often make a function with that code and learn to use conditional statements to control code execution, those who still want the goto function on matlab dont really know how to program.
