The parameter block is followed by the constants block.
A constant is declared and initialized at the same time, after which its value is fixed.
Constants can be initialized with the value of a parameter or a variable.
Const Text copiedfilename = destparameter["c:\temp",];
/* The constant sopiedfilename is initialized with the path/filename as stored in the destparameter. */
Const Number numberofcopies = Var1 + Var2;
/* The total of two Variable values is stored in a constant. */
