GO (Execute)
Usage: GO <addr>
The GO command executes target code starting at address addr. The value for addr may be an absolute
address specified as a hexadecimal value, or a symbol name.
If no argument is provided, the GO command begins executing instructions at the current program counter.
When the GO command is executed, all user-defined breakpoints are inserted into the target code, and the
context is switched to the target program. Control is only regained when the target code encounters a
breakpoint, illegal instruction, trap #15 exception, or other exception which causes control to be handed
back to dBUG.
The GO command is repeatable.
Examples:
To execute code at the current program counter, the command is:
go
To execute code at the C function main(), the command is:
go _main
To execute code at the address 0x0004_0000, the command is:
go 40000

GT (Execute To)
Usage: GT addr
The GT command inserts a temporary breakpoint at addr and then executes target code starting at the
current program counter. The value for addr may be an absolute address specified as a hexadecimal value,
or a symbol name.
When the GT command is executed, all breakpoints are inserted into the target code, and the context is
switched to the target program. Control is only regained when the target code encounters a breakpoint,
illegal instruction, or other exception which causes control to be handed back to dBUG.
