Note
In commands with RANGE specified as ADDR DEL ADDR,
and with size option W or L chosen, data at the second
(ending) address is acted on only if the second address is a
proper boundary for a word or longword, respectively.
Offset Registers
Eight pseudo-registers (R0 through R7) called offset registers are used to
simplify the debugging of relocatable and position-independent modules.
The listing files in these types of programs usually start at an address
(normally 0) that is not the one at which they are loaded, so it is harder to
correlate addresses in the listing with addresses in the loaded program. The
offset registers solve this problem by taking into account this difference
and forcing the display of addresses in a relative offset format.
Offset registers have adjustable ranges and may even have overlapping
ranges. The range for each offset register is set by two addresses: base and
top. Specifying the base and top addresses for an offset register sets its
range. In the event that an address falls in two or more offset registers’
ranges, the one that yields the least offset is chosen.
Note
Relative addresses are limited to 1MB (5 digits), regardless
of the range of the closest offset register.
