I was/am just looking for consistency. Sebastian cites the halcmd man page, which, it turns out, is inconsistent with the output from halcmd if one asks for "help linkps" or "help linksp". Unfortunately, that's where I started. Then, When I grepped emc2.5-dev/docs and ./src on '==>' I got around 100 hits (inflated, it turns out, by the multiple language files in docs). I must have made a mistake when I thought I did the same thing for '=>' (with attention paid to not double count '==>'), because I now get around 500 of them. That mistake led to my hyper-inflated and intemperate remark about "no where...except..." for which I apologize. Still, the argument that it's ok to do things inconsistently because "it really doesn't matter" rings hollow to me. One can never predict how someone is going to use this stuff. The great beauty of the Unix platform is the ease with which one can pipe data from one program to another. In my case, I've been writing a python script to generate component connection diagrams from halcmd output and it needs the "suitable for human consumption only" arrows to establish signal directionality. My code broke on some of the halcmd output because I believed what help told me. Now my code allows for both kinds of arrows, and I've moved on. All this would have been over in 30 seconds if we had been talking over a beer.
