• One space (ASCII code : 0x 20) is denoted by an underscore (_). Consecutive spaces
are denoted by alternating underscores (_) and overscores (¯).
• An I/O channel is expressed as a four-digit number (e.g., 0102), a math channel is
expressed as “A” followed by a three-digit number (e.g., A015), and a communication
channel is expressed as “C” followed by a three-digit number (e.g., C120).
