() ishi soichi () Sun, 29 Jul 2012 10:38:00 +0900 Could anyone point out the mistake I am making? Well, one mistake is posting HTML. I suppose that would be a "misgive", actually. There are others... this means the primary mistake is to ask for the (singular) mistake. But enough negativity. A better question is: What can the programmer do to explore this point in the behavior space, to find a path towards more desirable behavior? One idea: do ‘M-x toggle-debug-on-error RET’ first. -- Thien-Thi Nguyen ..................................... GPG key: 4C807502 . NB: ttn at glug dot org is not me . .
