A file is created that includes two computer programs. The first computer program is combined with a second computer program in the file, for example, by adding the first computer program to the file and appending the second computer program to the file. A file location identifier is included in the file. The file location identifier identifies a location of a division between the first and second computer programs in the file. The file may be stored in memory, and file location identifier may be used to identify a location of one of the computer programs in the memory.
