Load Map
The load map of a disk-resident command module contains the location of
control sections and entry points loaded into storage. Itmay also
contain certain messages and card images of any invalid cards or replace
cards that exist in the loaded files. The loadmap is contained in the
third record of theMODULE file.
This load map is useful in debugging. When using the Debug
environment to analyze a program, use the program's load map to help in
displaying information.
There are two ways to get a load map.
1. When loading relocatable object code into storage, make sure that
theMAP option is in effect when the LOAD command is issued. Since MAP is the default option, just be sure that NOMAP is not
specified.A load map is then created on the primary disk each
time aLOAD command is issued.
2. When generating the absolute image form of files already loaded
into storage, make sure that theMAP option is in effect when the GENMOD command is issued. Since MAP is the default option, just be
sure thatNOMAP is not specified. Issue the MODMAP command to type
the loadmap associated with the specified MODULE file on the
terminal. The format of theMODMAP command is: MODmap I filename

If an abend dump is desired whenCMS abnormally terminates, the terminal
operator must enter theDEBUG command and then the DUMP subcommand. The
dump formats and prints:• General registers • Extended control registers • Floating-paint registers • Storage boundaries with their corresponding storage protect key • Current PSW • Selected storage
Storage is printed in hexadecimal representation, eight words to the
line, with EBCDIC translation at the right. The hexadecimal storage
address corresponding to the first byte of each line is printed at the
