A range of numbers is submitted. If a number in the range is prime, it is multiplied by 1, otherwise multipliedby zero. Illustrates the topcode, maincode, and bottomcode in JSim function and procedure calls.

Description

Source functions and procedures written in Java take on the following forms
and incorporate source code that can be compiled at model build or model 
run time::
source real function name ( arguments ) { 
    language="java";
    topcode={{ 
        user-code 
    }}; 
    maincode={{ 
        user-code 
    }};
    bottomcode={{ 
       user-code 
    }}; 
}
source procedure name ( arguments ) { 
    language="java";
    topcode={{ 
        user-code 
    }}; 
    maincode={{ 
        user-code 
    }}; 
    bottomcode={{ 
        user-code 
    }}; 
}
The maincode block is required. topcode block, if used, can precede or follow
the maincode block. The same is true of the bottomcode block. The names
"maincode", "topcode", and "bottomcode" are the only names that are accepted
by JSim. In this model, there is a method to determine if a positive integer
is a prime. The method is placed in the topcode block to illustrate this
process. The use of topcode and bottom blocks is optional.

Equations

None.

The equations for this model may be viewed by running the JSim model applet and clicking on the Source tab at the bottom left of JSim's Run Time graphical user interface. The equations are written in JSim's Mathematical Modeling Language (MML). See the Introduction to MML and the MML Reference Manual. Additional documentation for MML can be found by using the search option at the Physiome home page.
