wishing for a 3-way loop construct

[Skaperen]

the way i figure i would deal with my pipeline issue is make a list of lists with the first 2 elements being False and False and the remaining element(s) describing the command.  then i would do list[0][[0],list[-1][1]=True,True.  then when i loop through the list to set up command processes and pipes like for this in cmdlist: i would have if this[0]: for one case and if this[1]: for the other.  this is simple enough, i think.
