Abstract
A program compiler identifies each symbol in a source program that references another program. For each identified symbol, the compiler determines whether the symbol is a reference to a remotely located file or to a locally stored file. If the identified symbol is a reference to a remotely located file, it constructs a file location identifier, such as a URL, for the identified symbol, performs a file location identifier based fetch of the remotely locate file, and ads at least a portion of the fetched file to a set of program code to be compiled if the fetch is successfully performed. If the identified symbol is a reference to a locally stored file, it performs a file fetch for the locally stored file, adding at least a portion of the fetched file to the set of program code to be compiled if the file fetch is successfully performed. If the fetch is unsuccessful, compilation of the source program is aborted. When a client computer attempts to initiate execution of a specified program, the program executed determines a source update date associated with a source program associated with the specified program and also determines if a compiled version of the source program is present o…
