#!CDarkGreen  #!Rall534 Expression Assignments #!N #!EC #!N #!N The values for 
the  #!F-adobe-times-bold-i-normal--18*   right-side #!EF portion of an expression assignment statement consist 
of a sequence of constant values, variables, arithmetic expressions, and the 
value  #!F-adobe-times-bold-r-normal--18*   NULL #!EF , separated by commas. The various values 
need not be of the same kind, data type, or dimension. 
#!N #!N The following examples all assign the value "A string" 
to the variable  #!F-adobe-times-bold-i-normal--18*   a #!EF , the value 2.0 to 
the variable  #!F-adobe-times-bold-i-normal--18*   b #!EF , and the value  #!F-adobe-times-bold-r-normal--18*   NULL 
#!EF to the variable  #!F-adobe-times-bold-i-normal--18*   c #!EF . #!N #!N #!CForestGreen 
#!N  #!F-adobe-courier-bold-r-normal--18*   #!N a = "A string"; // These 3 lines

#!EC #!N #!N The following example illustrates a simple way to 
swap values: #!CForestGreen #!N #!N  #!F-adobe-courier-bold-r-normal--18*   #!N a = 2; #!N 
b = 4; #!N c = 6; #!N d = 8; 
#!N e = 10; #!N a, b = b, a; // 
Values are swapped, so a = 4, b = 2 #!N 
c, d, e = e, c, d; // c = 10, 
d = 6, e = 8 #!EF #!N #!N #!EC #!N
