Hi to all. First of all thank you for your opinions. I'm Italian but I'm not a "stupid BASIC spaghetti programmers". [ ;-) ] Especially in CNC programming where usually the program flow from "top to bottom" and stops at the end with M2 (with no infinite loop as a void main ....) and you need to do a complex logical flow (conditional and unconditional) within the program to perform the various tasks (not essentially machining code) the GOTO statements are widely used. The fact that all the main CNC manufacturers include this kind of programming feature demonstrate that this way is far from obsolete but exactly the opposite. Also the "emblazoned" Haas machine manufacturer include the GOTO in their CNC G code programming language instruction set. Also the robot controllers programming languages (whatever brand) include the GOTO statements too. And , following the Chris opinion :
