/*
2.9.1.6 Added: Branch instructions now show target address
2.9.1.8 Changed: Disassembly window now lists symbol labels and symbol target address from User2 in orange.
Example:
U 300
SYM @ = 303
300: 20 03 03
2.9.1.7 Added: Extended SYM command to auto-generate symbol names when reverse engineering. NOTE: These symbols will be placed in User2.
Example:
SYM @ = 800 // Alias for: SYM _0800 = 0800
2.9.1.6 Added: Branch instructions now show target address.
2.9.1.5 Added: Disassembly window now shows signed decimal values for immediate values.
2.9.1.4 Changed: Show symbol warnings in Orange, and length of symbols in light blue.
2.9.1.3 Added: DB commanoptionally supports =
