negative GOTO block number

[SMAT]

Hi Scott,

I use GOTO with a negative block number.It doesn't work correctly.When the control FANUC read a negative block, it go backward. With NCPlot the negative just be ignore and NCPlot go forward to search next block's number.To cause me this problem:

OK, I will have another look at this. Sorry for the misunderstanding.

P.S. renumber function, not replace a GOTO's block number a with negative block

Thanks, I'll make a note of this.
