In this second example, two separate disk files are again created with independent ORG
values, but this time by using the SAV command. This command directs the assembler to
save all code assembled previous to the SAV code disk.

In this last example, just one file is created on disk, but the two blocks of code are
separated by approximately a $100 byte gap (less the size of the first code block, of
course).
Please read the section on SAV for more information about multiple ORGs in a program.
