Here are some examples, using the 23. 0o000027 Both the Debugger and MACRO-10 start out by assuming a default base (radix) of 8, so the value "27" is evaluated as an octal -number, and for convenience, the "print" command displays the result in both decimal and octal. You can change the default base +number, and for convenience, the "print" command displays the result in both octal and decimal. You can change the default base in the Debugger with the `s base` command (eg, `s base 10`), where the new base is always interpreted as a decimal number. This command differs from MACRO-10, which uses the `RADIX` pseudo-op to change the default base.
