地址以十六進(jìn)制數(shù)字輸入，例如20000對(duì)應(yīng)地址：00020000美元。地址或起始地址范圍的，可以由形式為^S、^S、^U或^U的后綴限定其中，S或S定義監(jiān)控器地址空間，U或U定義
用戶地址空間。默認(rèn)情況下，當(dāng)未指定限定符時(shí)，是主管。
一旦輸入了限定符，它對(duì)所有地址都有效輸入該命令序列，直到187Bug重新輸入或者提供了另一個(gè)限定符。地址的另一種形式是Rnn，它告訴bug使用包含在CPU寄存器Rnn中的地址，其中nn=00到31（即。，00, 01,..., 或31）。

Addresses are entered as a hexadecimal number, e.g., 20000 would
correspond to address $00020000. The address, or starting address
of a range, can be qualified by a suffix of the form ^S, ^s, ^U, or ^u
where S or s defines Supervisor address space, and U or u defines
user address space. The default, when the qualifier is not specified,
is Supervisor.
Once a qualifier has been entered, it remains valid for all addresses
entered for that command sequence, until the 187Bug is reentered
or another qualifier is provided.
An alternate form of Address is Rnn, which tells the bug to use the
address contained in CPU Register Rnn, where nn=00 thru 31 (i.e.,
00, 01,..., or 31). In commands with range specified as addr del addr, and
with size option H or W chosen, data at the second
(ending) address is acted on only if the second address
is a proper boundary for a half-word or word,
respectively. Otherwise, the range is truncated so that
the last byte acted upon is at an address that is a proper
boundaryEight pseudo-registers (Z0 through Z7) called offset registers are
used to simplify the debugging of relocatable and positionindependent modules. The listing files in these types of programs
usually start at an address (normally 0) that is not the one at which
they are loaded, so it is harder to correlate addresses in the listing
with addresses in the loaded program. The offset registers solve
this problem by taking into account this difference and forcing the
display of addresses in a relative address+offset format. Offset
registers have adjustable ranges and may even have overlapping
ranges. The range for each offset register is set by two addresses:
base and top. Specifying the base and top addresses for an offset
register sets its range. In the event that an address falls in two or
more offset registers' ranges, the one that yields the least offset is
chosen.
Note Relative addresses are limited to 1MB (5 digits),
regardless of the range of the closest offset register.
Port Numbers
Some 187Bug commands give the user the option to choose the port
to be used to input or output. Valid port numbers which may be
used for these commands are:
1. MVME187 EIA-232-D Debug (Terminal Port 0 or 00) (PORT 1
on the MVME187 P2 connector). Sometimes known as the
“console port”, it is used for interactive user input/output by
default.
2. MVME187 EIA-232-D (Terminal Port 1 or 01) (PORT 2 on the
MVME187 P2 connector). Sometimes known as the “host
port”, this is the default for downloading, uploading,
concurrent mode, and transparent modes
