--EXPR--
An expression is a combination of numeric values, symbols, operators, and
parentheses, specifying an offset value to be subtracted from the addresses
traced by the emulation analyzer. See the EXPR syntax diagram.
external
binary
Displays the external analyzer trace list in binary format.
<external
_label>
This option displays a defined external analyzer label.
hex Displays the external analyzer trace list in hexadecimal format.
off Use this option to turn off the external trace list display.
then
This allows you to display multiple external analysis labels. This option
appears when more than one external analyzer label is in use.
<LINE#>
This prompts you for the trace list line number to be centered in the display.
Also, you can use <LINE#> with disassemble_from_line_number. <LINE#>
prompts you for the line number from which the inverse assembler attempts
to disassemble data in the trace list.
mnemonic Lists trace information with opcodes in mnemonic format.
offset_by
This option allows you to offset the listed address value from the address of
the instruction. By subtracting the offset value from the physical address of
the instruction, the system makes the listed address match that given in the
assembler or compiler listing.
This option is also useful for displaying symbols and source lines in
dynamically relocated programs.
Note that when using the set source only command, the analyzer may
operate more slowly than when using the set source on command. This is an
operating characteristic of the analyzer:
When you use the command set source on, and are executing only
assembly language code (not high-level language code), no source
lines are displayed. The trace list will then fill immediately with the
captured assembly language instructions.
When using set source only, no inverse assembled code is displayed.
Therefore, the emulation software will try to fill the display with
high-level source code. This requires the emulation software to search
for any captured analysis data generated by a high-level language
statement.
In conclusion, you should not set the trace list to set source only when
tracing assembly code. This will result in optimum analyzer performance.
