The Memory Map
The memory map supplies useful information about segment placement and address
assignment. Figure 5-3 shows LOC86's memory map.
The map consists of three parts:
• Header
• Segment map
• Group map
The header includes the input module name and the start address.
The segment map is a table with six columns. From left to right the columns show:
• the START address of the segment
• the STOP address of the segment
• the LENGTH of the segment
• the ALIGNMENT attribute of the segment
• the NAME of the segment
• the CLASS of the segment
• the OVERLAY of the segment
A "C" printed between the STOP and LENGTH columns indicates that two
segments have overlapping memory locations; a warning message is also issued.
A segment may have anyone of the following alignment attributes:
A
absolute
B byte
G
paragraph
M
member of an L TL group
P page
W word
R
in-page
