it is called a high level object and the different packages
create a lot of it, eg \psGaus from package pst-func;

\define at key[psset]{pst-func}{sigma}{\def\psk at sigma{#1 }}
\define at key[psset]{pst-func}{mue}{\def\psk at mue{#1 }}
\psset[pst-func]{sigma=0.5,mue=0}
%
\def\psGauss{\@ifnextchar[{\psGauss at i}{\psGauss at i[]}}
\def\psGauss at i[#1]#2#3{{%
     \pst at killglue%
     \psset{plotpoints=200}%
     \psset{#1}%
     \psplot{#2}{#3}{%
         Euler x \psk at mue sub dup mul 2 div \psk at sigma dup mul div neg exp
         1.0 \psk at sigma div TwoPi sqrt div mul%
     }%
}\ignorespaces}
