ABSTRACT:
The system and method of the present invention automatically converts field lengths of data fields in a data file that are accessed by a computer program and correspond to date-related data. Either the computer program or the data file may be non-compliant. This function is carried out by providing a control program including parameters and commands for converting the field length of a date-related data field in the data file, inserting codes in the computer program file including a subroutine calling command such that the control program will be called and executed as a subroutine from within the computer program file, executing the computer program file, and executing the control program when the computer program executes the subroutine calling command to automatically convert the field length of a date-related data field identified by the computer program in order to allow either inclusion or exclusion of the century in a portion of the data field indicating the year prior to manipulation of the date-related data by the computer program. The control program may be executed on-line or in batch when the computer program executes the subroutine calling command. The step of providing the control program includes inserting file conversion parameters into a model control program to generate a control program file, and compiling the control program file to generate the control program.
