Right. > Is the aLength parameter designed to mean raw character counts, or > character/number positions? Would > "U12" compare smaller to "U2" at aLength == 2? Please consider aLength as the count of characters to take in account. (I mean "U12" compare to "U2" at aLength == 2 compare "U1" and "U2") > Cases like "U12A4A3" vs. "U12A4A4" are also specified where the latter would > compare "greater", yes? > > Michael Yes, although is is a corner case, but it can happens. -- Jean-Pierre CHARRAS _______________________________________________ Mailing list: https://launchpad.net/~kicad-developers Post to : [email protected] Unsubscribe : https://launchpad.net/~kicad-developers More help : https://help.launchpad.net/ListHelp
