The assembler also produces a log file plus files that show the assignments for various
labels and constants found in the source code. The log file shows the instruction address,
the opcode for each instruction, and the source code instruction and comments for the
associated instruction address. The assigned values for register names, labels, and
constants appear immediately following the associated symbolic name.
Finally, the KCPSM3 assembler generates a formatted version of the source program
(“pretty print” output). The formatted output file formats all labels and comments,
converts all commands and hexadecimal constants to upper case, and consistently spaces
operands.
