Syntax: startaddress endaddress
startaddress L count
An "address range" is a pair of memory addresses that specify the
higher and lower boundaries of a sequence of contiguous memory
locations. You can specify a range in two ways:
1. Give the starting and ending points:
startaddress endaddress
In this case, the range covers <startaddress> to
<endaddress>, inclusively. If you don't supply an
<endaddress>, CodeView assumes the default range. Each
command has its own default range; the most common default
range is 128 bytes.
2. Give the starting point and the number of objects you want
included in the range:
startaddress L count
This type of range is called an "length range." The
<startaddress> is the address of the first object in the
list, and <count> specifies the number of objects in the
range. The size of the objects is the size taken by the
command. For example, the Dump Bytes (DB) command has byte
objects, the Dump Words (DW) command has words, the
Unassemble (U) command has instructions, and so on.
