#!EC The  #!F-adobe-times-medium-i-normal--18*   positional #!EF argument-passing mechanism is similar to the 
mechanism found in most programming languages that use subroutines. Given a 
function declared with  #!F-adobe-times-medium-i-normal--18*   n #!EF input formal parameters, the first 
 #!F-adobe-times-medium-i-normal--18*   n #!EF values supplied in the function call are assigned 
to the first  #!F-adobe-times-medium-i-normal--18*   n #!EF formal parameters. If you supply 
 #!F-adobe-times-medium-i-normal--18*   i < n #!EF values in the function call, then 
only the first  #!F-adobe-times-medium-i-normal--18*   i #!EF of the function's formal parameters 
are assigned the supplied values. #!N #!N The missing arguments are 
assigned the value of  #!F-adobe-times-bold-r-normal--18*   NULL #!EF . #!N #!N #!N
