A.2 Introduction
The MCUez HC12 assembler has been extended to ensure compatibility with
the MASM assembler.
A.3 Comment Line
A line starting with an asterisk (*) character is considered to be a comment line.
A.4 Constants
For compatibility with MASM, these integer constant notations are supported:
• Decimal constants are a sequence of decimal digits (0–9) followed by d
or D.
• Hexadecimal constants are a sequence of hexadecimal digits (0–9, a–f,
A–F) followed by h or H.
• Octal constants are a sequence of octal digits (0–7) followed by o,O,q,
or Q.
