From the Windows menu, choose Memory 1 or Memory 2.Memory windows display memory in a number of formats. CodeView allows two Memory windows to be open at the same time. You can open a Memory window in several ways:
From the Windows menu, choose Memory 1 or Memory 2.
From the Options menu, choose Memory1 Window when no Memory windows are open.
In the Command window, enter the View Memory (VM) command.
At the keyboard, press ALT+5 or ALT+6.
By default, memory is displayed as bytes or as the last type specified by a Memory Enter (ME), Memory Dump (MD), or View Memory (VM) command. The byte display shows hexadecimal byte values followed by an ASCII representation of those byte values. For values that are outside the range of printable ASCII characters (decimal 32 to 127), CodeView displays a period (.).
How to Change Memory Display Format
It is not always most convenient to view memory as byte values. If an area of memory contains character strings or floating-point values, you might prefer to view them in a directly readable form.
To change the display format of a Memory window, choose Memory1 Window or Memory2 Window from the Options menu. CodeView displays a dialog box where you can choose from a variety of display options. When the cursor is in a Memory window, you can presss CTRL+O to display the corresponding Memory Window Options dialog box. You can also set memory display options using the View Memory (VM) command. For detailed information about the display options, see “View Memory” on page 455.
To cycle through the display formats, click the <Sh+F3=Mem1Fmt> or <Sh+F3=Mem2 Fmt> buttons on the status bar, or press SHIFT+F3. Pressing CTRL+SHIFT+F3 displays the cycle in reverse order.
When you first open the Memory window, it displays memory starting at address DS:00. To change the starting address, use one of the commands to set Memory window options. You can specify the starting address or enter an expression to use as the starting address.
You can also type over the segment:offset addresses shown in the left column of the Memory window to change the displayed addresses. Move the cursor to an address in the window, or repeatedly press TAB until the cursor is on an address, and type a new address.
To change the values in memory, overtype the value you want to change. To move quickly from field to field in the Memory window, press TAB. You can change memory by entering new values for the format that is displayed or by typing over the raw bytes in the window. CodeView ignores the input if you press a key that does not make sense for the current format (for example, if you type the letter X in anything but ASCII format).
To undo a change to memory, choose Undo from the Edit menu, or press ALT+BACKSPACE.
How to View Memory at a Dynamic Address
Live expressions make it easy for you to watch a dynamic view of an array or pointer in the Memory window. “Live” means that the starting address of memory in the window changes to reflect the current value of an address expression.
To create a live expression, choose the Memory1 Window or Memory2 Window command from the Options menu. In the Memory Window Options dialog box, type in an address expression, then turn on the Re-evaluate Expression Always (Live) option.
It is usually more convenient to view an item in the Watch window than in the Memory window. However, some items are more easily viewed using live expressions. For example, you can examine what is currently on top of the stack by entering SS:SP as the live expression.
