Keywords may appear in any order. Here is an example of command-line defaults using keywords.
ICL> picdef current fraction=0.4
FRACTION is a real parameter. CURRENT is a logical parameter; by giving just its name it is assigned the value TRUE. CURRENT=T would have the same effect. To obtain a FALSE value for a logical parameter you add a NO prefix to keyword, for example,
icl> picdef nocurrent
would be equivalent to the following.
icl> picdef current=false
