Table 3–10 Display Command Qualifiers
Command Display Mode
D[isplay]/b Byte (default)
D[isplay]/w Word
D[isplay]/d Doubleword
D[isplay]/a ASCII
If you do not designate an address, the system defaults to the last address
selected for display or to address 0 if no previous display command was
executed.
Addresses have the format task:seg:offset. The task:seg fields are optional,
but are always displayed by the system. The offset field is required and is the
address offset within the segment. For example, to display the data in the byte
display mode (default) at address location 32F (hex) in segment 8 (default), use
either of the following:
HLT> display 32f
Enter
0:8:32F 53
HLT> display 0:8:32f
Enter
0:8:32F 53
You can also specify an argument list to display an address range. The range
can be any size from one unit or more and can be in ascending or descending
order. The range is specified as addr addr (starting address, ending address)
or as addr length value (starting address, length qualifier, length value in
display mode units).
In addr addr mode, the ending address is another offset within the segment. If
the ending offset (address) is greater than the starting offset, then memory is
displayed in order of ascending addresses. If the ending offset is less than the
starting offset, data is displayed in descending order.
In addr length value mode, the length value specifies how many units (byte,
word, and so on) of data to display beginning with the starting address. If
the length is a positive number, data is displayed in ascending addresses.
A negative length displays addresses in descending order. For example, to
display eight doublewords of data beginning at location 32FH in segment 8
(default), use the following:
HLT> display/dword 32f length 8
Enter
0:8:32F F000FF53 F000FF53 F105ED41 F000FF53
0:8:33F F000FF53 F000EDF2 F0008C8C F000FF53
