Examples and Tests:

HELLO is just a "Hello, world!" program. Files you may copy include:

• hello.f, the source code;
• hello.csh, commands that compile and run the source code;
• hello.ll, an IBM RS/6000 LoadLeveler input file that runs the source code;
• hello_output.txt, the output file;

RANDOM_NUMBERS shows one way to generate random numbers, given that FORTRAN77 does not specify a built in random number generator. Files you may copy include:

• random_numbers.f, the source code;
• random_numbers.csh, commands that compile and run the source code;
• random_numbers_output.txt, the output file;
