5.3Data Window Commands

The Data Window displays an area of memory in hexadecimal format and, if the window is wide enough, an ASCII trans- lation. (See Section 3.6, “The Data Window”.) The commands to adjust the Data Window are similar to those for the Pro- gram Window and are described below.

5.3.1Summary of Data Window Commands

dj [address]

If address is speciﬁed, repositions (“jumps”) the Data Window so that the bytes containing the speciﬁed address are ﬁrst in the window. If no address is given, jumps to the previous location. The mnemonic stands for “data jump”.

df [count]

Moves the Data Window forward count display lines or one windowful if count is not speciﬁed. The mnemonic stands for “data forward”.

db [count]

Moves the Data Window backward count display lines or one windowful if count is not speciﬁed. The mnemonic stands for “data backward”.

dbndl

Displays the data as hexadecimal instruction bundles, as shown in Figure 5-4and in Figure 3-15, “xski’s Data Window Showing Data Interpreted as Instruction Bundles,” on page 3-11.It is your responsibility to ensure that the Data Window is actually positioned on instructions; if not, Ski will dutifully display nonsense. The ﬁrst column displays the address. The second column displays the template ﬁeld. The remaining three columns display the 41-bit instructions from slots 0, 1, and 2, with the least-signiﬁcant bit to the right. The mnemonic stands for “data window bundle”.

dh

Displays the data as raw hexadecimal with an ASCII translation, as shown in Figure 5-5.The mnemonic stands for “data window hexadecimal”.
