Program generation apparatus for program execution system, replaces variable name in each class file by assigned offset number so that same offset numbers are assigned to non-dependent variables with same variable name

A program generation method for use in a program generation apparatus which generates a plurality of light-weight class files for each terminal apparatus by linking a plurality of class files for each terminal apparatus, the program generation apparatus including

• a storage means for prestoring the plurality of class files for each terminal apparatus, wherein each class defines (a) dependent variables unique to each terminal apparatus and (b) non-dependent variables common to all the plurality of terminal apparatuses, each variable is identified by a variable name, and each class file includes a variable name for each variable, and the program generation method comprising:
• an assignment step for, when a plurality of class files are linked for a terminal apparatus in relation to other terminal apparatuses, assigning an offset number to each variable defined in the plurality of class files so that the same offset numbers are assigned to non-dependent variables having the same variable names for the other terminal apparatuses;
• and
• a generation step for generating the plurality of light-weight class files for each terminal apparatus by replacing each variable name in each class file with an offset number assigned in the assignment step.

A computer-readable record medium recording a computer program for use in a computer which generates a plurality of light-weight class files for each terminal apparatus by linking a plurality of class files for each terminal apparatus, the computer including

• a storage means for prestoring the plurality of class files for each terminal apparatus, wherein each class defines (a) dependent variables unique to each terminal apparatus and (b) non-dependent variables common to all the plurality of terminal apparatuses, each variable is identified by a variable name, and each class file includes a variable name for each variable, and the computer program comprising:
• an assignment step for, when a plurality of class files are linked for a terminal apparatus in relation to other terminal apparatuses, assigning an offset number to each variable defined in the plurality of class files so that the same offset numbers are assigned to non-dependent variables having the same variable names for the other terminal apparatuses;
