Provided is a method, system, and program for generating and communicating information on locations of program sections in memory. Source code is generated for an agent program. The source code includes start and end variables for selected sections of the program, wherein the start and end variables for each selected section are used to indicate the start and end address in a memory at which the section is loaded. The selected sections are capable of including less than all the sections in the program. The source code is compiled and linked to generate an object file including the sections. The object file causes, in response to being loaded into the memory of a computer, a relocation of at least one of the start and end memory addresses of the selected sections into at least one of the start and end variables for the selected sections when memory addresses are assigned to sections as part of relocation operations. Other embodiments are disclosed and claimed.
