memory location 0x0022, which has a value of 0xFF. This information is given in the fly-over text and
also in the titlebar. Either or both of these options may be disabled by right clicking in the Memory
Dump window or in the Options | Environment Options, Debug Windows tab, under Specific Prefer-
ences for the Memory Dump window.
Memory Dump windows may be scrolled. Scrolling causes the contents of other memory addresses to
appear in the window. Hotkeys ArrowUp, ArrowDown, PageUp, PageDown are active in the Memory
Dump window. The window always displays as many lines of 16 bytes and their ASCII equivalent as
will fit in the window.
Values in the Dump window are updated automatically when Dynamic C stops or comes to a break-
point. Updates only occur if the window is updateable. This can be set either by right clicking in the
Memory Dump window and toggling the updateable menu item, or by clicking on the Debug Windows
tab in Options | Environment Options. Select Memory Dump under Specific Preferences, then check
the option “Allow automatic updates.” The Memory Dump window can be updated at any time by
clicking the Update button on the tool bar or by right clicking and choosing Update from the popup
menu.
The Memory Dump window is capable of displaying three different types of dumps. A dump of a logi-
cal address ([0x]mmmm) will result in a 64k scrollable region (0x0000 - 0xffff). A dump of a physical
address ([0x]mmmmm) will result in a dump of a 1M region (0x00000 - 0xfffff). A dump of an
xpc:offset address (nn:mmmm) will result in either a 4k, 64k, or 1M dump range depending on the
option set on the Debug Windows tab under Options | Environment Options.
Note that adding a leading zero to a logical address makes it a physical address.
Any number of dump windows may be open at the same time. The type of dump or dump region for a
dump window can be changed by entering a new address in the toolbar’s text entry area. To the right of
the this area is a button that, when clicked, will cause the address in the text entry area to be the first
address in the Dump window. The toolbar for a dump window may be hidden or visible.
