Computer system and method for producing program code

The present invention relates to a method for producing program code to describe several function names of a device and correspondent relationship between several control signal codes. Said method includes the following steps: receiving several function names and correspondent relationship of several control signal codes, detecting that every function name is correspondent to several control signal codes or not and detecting that every control signal code of several control signal codes correspondent to several function names of correspondent to several function names or not. If some function name is correspondent to several control signal codes, the warning can be given out to make user define that a program code for describing correspondent relationship is required to be produced or not according to said correspondent relationship; and if in the several control signal codes correspondent to several function names there is not any control signal code correspondent to several function names, the program code for describing correspondent relationship can be produced according to the correspondent relationship.
