mnem The mnemonic for an instruction.<br />

code An interrupt code number in hexadecimal.<br />

name An interrupt name (for example, operation, addressing).<br />

CC n The condition code number (0, 1, 2, or 3).<br />

Note: The condition code will not always be displayed.<br />

Gnn A general register with altered contents.<br />

cccccccc<br />

cccccccccccccccc<br />

cccccccc_cccccccc<br />

The address generated <strong>and</strong> loaded by a LOAD ADDRESS or LOAD<br />

ADDRESS EXTENDED instruction. 2<br />

ss A status byte.<br />

FSA=nnnnnnnn<br />

FSA=nnnnnnnnnnnnnnnn<br />

FSA=nnnnnnnn_nnnnnnnn<br />

The failing storage address if valid. If it is not valid, nothing is<br />

shown. 2<br />

zz An altered byte of an EXECUTE instruction, formed by<br />

inclusive-ORing the low byte of R1 with the second byte of the<br />

executed instruction.<br />

*** A prefix indicating virtual machine interrupt.<br />

-> As a prefix indicating transfer of control, this symbol is present at<br />

the beginning of a line whenever the displayed instruction does not<br />

immediately follow the last instruction displayed. As a suffix for a<br />

successful branch instruction, it precedes the address being<br />

transferred to.<br />

>> An indication of storage alteration, followed by the oper<strong>and</strong><br />

address.<br />

- A suffix used on storage oper<strong>and</strong> addresses to indicate that the<br />

address being displayed is one byte past the end of the storage<br />

altered by the instruction.<br />

= A prefix used with LOAD ADDRESS or LOAD ADDRESS<br />

EXTENDED to show that the actual data is shown rather than<br />

computing the oper<strong>and</strong> address by base <strong>and</strong> displacement.<br />

ARareg An access register with altered contents.<br />

TRACE: Comm<strong>and</strong> Responses<br />

SPACEowner:space_name<br />

identifies the owner’s user ID <strong>and</strong> the name of the address space in<br />

which the trace event occurred. It is displayed only for XC virtual<br />

machines.<br />

ASITasit identifies the address space identification token of the address<br />

space in which the trace event occurred. It is displayed only for XC<br />

virtual machines.<br />

For operation codes that represent two mnemonics, the mnemonic for fixed-point<br />

operations is shown. The following is a list of those operation codes with the<br />

mnemonic to be returned by <strong>CP</strong>:<br />
