/MAP[:filename]
Remarks
where:
- filename
 A user-specified name for the mapfile. It replaces the default name.
Remarks
The /MAP option tells the linker to create a mapfile.
By default, the linker names the mapfile with the base name of the program and the extension .map. The optional filename allows you to override the default name for a mapfile.
A mapfile is a text file that contains the following information about the program being linked:
- The module name, which is the base name of the file 
- The timestamp from the program file header (not from the file system) 
- A list of groups in the program, with each group's start address (as section:offset), length, group name, and class 
- A list of public symbols, with each address (as section:offset), symbol name, flat address, and .obj file where the symbol is defined 
- The entry point (as section:offset) 
The /MAPINFO option specifies additional information to be included in the mapfile.
