Abstract

A program partial linking system includes an assigned program existence judgement section, an assigned program linkage section, and a specific program linkage section. The assigned program existence judgement section judges whether the program assigned by linkage information input during program linkage exists in a program library. The assigned program linkage section links the assigned program when the judgement section judges that the assigned program exists in the program library. The specific program linkage section links a specific program prepared in advance when the judgement section judges that the assigned program does not exist in the program library.

Claims

1. A program partial linking system, comprising:

program storing means for storing incomplete programs and additional programs, said incomplete programs requiring execution of at least a corresponding program of said additional programs for completion;

means for providing a single replacement program for all said additional programs;

input means requiring execution of said incomplete programs;

searching means, coupled to said input means and to said program storing means, responsive to said input means for searching for said additional programs in said storing means and providing a search result;

means, coupled to said searching means and to said means for providing, responsive to said search result including means responsive to an indication of non-existence of said corresponding program in said storing means for outputting said single replacement program from said means for providing said single replacement program;

wherein said means responsive to said search result includes means responsive to an indication of an existence of said corresponding program in said storing means for outputting said corresponding program; and

a linked program output file, coupled to said means for outputting said single replacement program and said means for outputting said corresponding program, for receiving said single replacement program from said means for outputting said single replacement program and said corresponding program from said means for outputting said corresponding program.

2. A program partial linking system, comprising:

program storing means for storing a plurality of programs including a plurality of a first type of unit programs each requiring execution of at least an additional unit program of a plurality of a second type of unit programs;

means for providing a single specific program as a replacement for all unit programs of said second type;

data input means for providing input data identifying one program of said first type of unit programs and a storage location of said one program in said program storing means;

means, coupled to said data input means and said program storing means, for decoding said input data, retrieving said one program from said program storing means and determining thereform linkage information including an identity of said additional unit program;

storage means, coupled to said means for decoding, for storing said linkage information;

searching means, coupled to said storage means and said program storing means, responsive to said identity from said storage means for searching said program storing means for said additional unit program to provide a search result;

means, coupled to said program storing means and said searching means, for retrieving said additional unit program from said program storing means in response to said search result indicating said additional unit program exists in said program storing means;

means, coupled to said means for providing a single specific program and to said searching means, for outputting said single specific program in response to said search result indicating said additional unit program does not exist in said program storing means; and

file means, coupled to said means for retrieving and said means for outputting, for receiving said additional unit program from said means for retrieving or said single specific program from said means for outputting depending on said search result.
