A computer system, program product, and method utilize alternate program code associated with an executable file using a file attribute so that the alternate program code may be retrieved and executed in lieu of the primary program code stored in the file. As one example, for a platform-independent executable file such as a Java class file, a file attribute of the file may be analyzed to determine if native program code for a particular platform is associated with the file. If so, the native program code may be retrieved and executed directly without the additional overhead associated with interpreting the platform-independent program code in the file. If, on the other hand, the native program code is not detected, the native program code may be generated and associated with the file using a file attribute such that the native program code is detected in subsequent attempts to retrieve and execute the file.
