The first question is how you would define the target position. As LinuxCNC G-code doesn't pay attention to line numbers I think you would need two new keywords, both the GOTO expression and the target. O100 LABEL maybe? In the interpreter at the moment the loop ends are matched by number. O100 while -> O100 endwhile etc. In the context of GOTO it guess that you would need an O101 GOTO to jump to your O101 LABEL. But, this leaves no scope for the (I shudder to mention this even amongst GOTO advocates) computed GOTO. O[#1 + 200] GOTO isn't valid syntax, I don't think. As a less-than-transparent workaround you can currently use O100 WHILE [0] to jump to an O100 ENDWHILE, but I don't know if you can jump backwards, and I don't know if you can have more than one WHILE per ENDWHILE. For many of the applications that have been mentioned here, the O100 REPEAT[] statement will work. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ Meet PCI DSS 3.0 Compliance Requirements with EventLog Analyzer Achieve PCI DSS 3.0 Compliant Status with Out-of-the-box PCI DSS Reports Are you Audit-Ready for PCI DSS 3.0 Compliance?
