BASE Command
Example
For trace breakpoint examples, see Appendix F, Sample Debug Sessions.
Format of the Command-String Display
For an execute mode breakpoint (code or memory-access), Debug displays the value
of command-string that was entered with the breakpoint.The command-string
parameter is displayed in this form:
BASE Command
The BASE command changes the default base for numeric values displayed by Debug
and accepted by Debug as command input. The form of the BASE command is:
STANDARD | S
Generally, input and output base defaults are determined by each command:
•
Hexadecimal for the DN command and commands that use the N-address
mode.
•
Octal for most other commands.
The default base is STANDARD for both the IN and OUT options.
OCTAL | O
specifies that octal is the base for input or displayed numeric values.
DECIMAL | D
specifies that decimal is the base for input or displayed numeric values.
HEXADECIMAL | H
specifies that hexadecimal is the base for input or displayed numeric values.
index is an offset from the base address. It can be used with 16-bit
addresses only.
? is the trace indicator.
count is the number of 16-bit words to be displayed.
