The Test

This test program is designed to benchmark the passing of large character data to a subprocedure. To call this program simply call it from a command line. The program will perform each check and print out the average call times per 100 calls for each check. There are 2 optional parameters. The first parameter will instruct the program to perform that number of calls for each test. The second parameter will instruct the program to print the call time as the average time taken to perform that number of calls. The default for the two parameters is 10,000 and 100. That is, the program will call each subprocedure 10,000 times and give the average time taken to call each subprocedure 100 times.

The results will be displayed on the terminal.
