Automatic program generating apparatus using skeletons having fixed instruction areas and undefined instruction areas

Claim 1

An automatic program generating apparatus comprising: storage means for storing a plurality of skeletons, each serving as a framework for generating a program and having fixed instruction areas and undefined instruction areas, where the undefined instruction areas are designated by a flag; display means for displaying an identification code and a description for each of the plurality of skeletons stored in said storage means; selecting means for inputting the identification code of one of the stored plurality of skeletons; readout means for reading out the skeleton corresponding to the selected identification code; input request means for requesting data in a predetermined order, said data used in generating instructions for each undefined instruction area of the readout skeleton; said input request means comprising: means for sequentially checking instructions in the readout skeleton to detect whether the flag is present in the instructions, and means for causing said display means to display a data input request message when the flag is detected; creation means for creating an address map representing a correspondence between the instruction addresses of the readout skeleton before instructions are inserted in said undefined instruction areas and the instruction addresses of the readout skeleton after instructions are inserted in said undefined instruction areas; first detection means for detecting a program end instruction in the readout skeleton; second detection means for detecting jump instructions in the readout skeleton; correction means for correcting each jump instruction in accordance with the address map; and automatic coding means for creating a machine language program after the undefined instruction areas of the readout skeleton are filled with instructions.
