HCPLDR Control Statements and Output
Table 29. Load Map Contents (continued)
Label Contents for Modules (CSECTs) Contents for Entry Points
(Blank) SD A reference code:
–– The entry point is unreferenced.
.. The entry point is referenced by an
EXTRN but not by any address
constant.
(blank) The entry point is referenced by an
EXTRN with an address constant
(most CP entry points fall into this
category).
LOAD The load address of the module The load address of the entry point
ASM The offset of the module name within the
module (for CP, this is usually 0)
SIZE The size of the module (Blank)
(Blank) Normally blank. ? if an attempt was made to
define the symbol twice.
The offset of the entry point within the module
Normally blank. ? if an attempt was made to
define the symbol twice.
Load Map Sorted by Address
This report contains the same information as the Load Map Sorted by Name, but it
is sorted by the load address of the module or entry point.
You can use this report to check the starting and ending addresses of your
generated system and verify that modules were loaded in the correct order.
Other Information
Figure 19 shows an example of the last report from a CP load map. It shows:
v The number of failures of any VERIFY loader control statements contained in the
system.
Your system should not have any verify failures. Since VERIFY and REPLACE
loader control statements are most often used to replace object code in a text
deck, a verify failure probably indicates an error in the resulting code.
v The number of unreferenced CSECTs and their names.
v The relocation summary. The relocation summary shows the number of
references by length (1, 2, 3, and 4 bytes).
For CP, all of the references are 4 bytes long (AL4s).
NO VERIFY FAILURES
12 UNREFERENCED CSECTS: HCPADP HCPCCW HCPCHS HCPCIO HCPDCTCT HCPDDP H CPDD1 HCPDUP HCPFCP
HCPGCS HCPGCSLV HCPGIS
RELOCATION SUMMARY: 24,355 AL4’S

SMALLMAP File Information
If the SMALLMAP option is used, HCPLDR will produce a file with the following
characteristics. The example given is for a CP system and Figure 20 on page 1913
shows an excerpt of its contents.
