An assembler translates assembly code into object code.

Should support lables:

• 100 goto label
• 130 label

should support comments:

• ;comments

Should support naming of registers

• SunReg EQU 5 (definable or not redefinable)
• CLRF SunReg

should support program counter setting

• ORG 100 =next line of code = line 100

should allow number to be decimal, (default) hex(end in H), octal (end in O), binary(end in B). Expressions are extra credit.

www.microchip.com for assembly code.

Need to build table of symbols and values then actually generate code (2 pass). Could also do pass assembler by filling in values as you find them. (extra credit)

objects

• lines, symbols, object code, instructions, op codes...
