I have still to see an instruction set that does not have some form of call some code elsewhere and return to this same place. ( with more or less state saving ) AND: goto is definitely not control of programm flow. If, while, ... or jump bit set, branch on zero .... with the most primitive being "skip next cmd on <flag>" thats control of programm flow. uwe

Yes, instruction sets are much richer as necessary. I also count these conditional jump instructions as goto, as also in fortran I need the if and not only the goto for the control flow. You understood the issue. But the question: Would you like a goto in Tcl or not? Rodrigo.

You seem rather generous in labeling things "goto" ;-) I get the impression that the "goto" you are looking for is [switch]. Now the c goto usage I seem to see the most is the unraveling of successive dependent actions. Now, with the duality of code and data in tcl you can take a better hammer from your toolkit. Not much need for goto. uwe
