Section 9.1: The history of assembler programs (Frame 4)                     [prev][home][next]

Since the computer cannot execute these programs directly the assembler must translate the program into a file containing executable instructions. Such a file is called an object file or object program, and the original program is called the source file or source program. Here is the object file corresponding to the assembler program on page 1 as it would appear in the CSC-1's memory, both in binary and as decimal numbers:

    as binary...        as decimal...

0000 0000 0000 0100            4
0011 0000 0000 0101        12293
0001 0000 0000 0110         4102
1111 1001 0000 0000        63744
0000 0000 0000 0101            5
0000 0000 0000 0111            7
0000 0000 0000 0000            0

These values are found in words 0 through 6. Addresses are not shown. Word 0 is first and word 6 is last.
