Also, does someone know how to To define \mycommand[.1.][.2.]{.3.}? E, i.ge., with curly braces around a non-optional third argument? , you just define  I think this just involves adding a second, non-delimited argument to <tt>\doMyCommand</tt>, but I'm not sure. def\mycommand{\dodoubleempty\doMycommand} Also, can \def\doMycommand[#1][#2]#3{whatever} ---- Can someone test to see if <tt>\dosingleempty</tt> and <tt>\dodoubleargument</tt> can be chained, to get two square-bracketed arguments only one of which is optional?
