You can use the <Up arrow>, <Down arrow>, <PREV>, and <NEXT> keys to
view the displayed information. For software_breakpoints, data, memory, and trace
displays you can use the <CTRL>g and <CTRL>f keys to scroll left and right if the
information goes past the edge of the screen.
Depending on the information you select, defaults may be the options selected for
the previous execution of the display command.
The parameters are as follows:
,
A leading comma allows you to append additional expressions to the previous
display data command. Commas between expression/data type specifications allow
you to specify multiple variables and types for display with the current command.
<CLASS> Specifies a particular class of the emulator registers. Refer to the "Accessing
Registers" section in the "Using the Emulator" chapter for a list of the register
names and classes.
data You can display the values of simple data types in your program. This command
can save you time; otherwise, you would need to search through memory displays
for the location and value of a particular variable.
The address, identifier, and data value of each symbol may be displayed. You must
issue the command set symbols on to see the symbol names displayed.
In the first display data command after you begin an emulation session, you must
supply at least one expression specifying the data item(s) to display.
Thereafter, the display data command defaults to the expressions specified in the
last display data command, unless new expressions are supplied or appended (with
a leading comma).
Symbols are normally set off until you give the command set symbols on.
Otherwise, only the address, data type, and value of the data item will be displayed.
error_log
This option displays the recorded list of error messages that occurred during the
emulation session.
event_log This option displays the recorded list of events.
--EXPR--
An expression is a combination of numeric values, symbols, operators, and
parentheses, specifying the data item to display or an offset value for the breakpoint
address. See the --EXPR-- syntax diagram.
