Flat-File APIs

JD Edwards EnterpriseOne APIs such as jdeFprintf() convert data. This means that the default flat file I/O for character data is in Unicode. If the users of JD Edwards EnterpriseOne-generated flat files are not Unicode enabled, they will not be able to read the flat file correctly. Therefore, use an additional set of APIs.

An interactive application allows users to configure flat file encoding based on attributes such as application name, application version name, user name, and environment name. The API set includes these file I/O functions: fwrite/fread, fprintf/fscanf, fputs/fgets, and fputc/fgetc. The API converts the data using the code page specified in the configuration application. One additional parameter, lpBhvrCom, must be passed to the functions so that the conversion function can find the configuration for that application or version.

These new APIs only need to be called if a process outside of JD Edwards EnterpriseOne is writing or reading the flat file data. If the file is simply a work file or a debugging file and will be written and read by JD Edwards EnterpriseOne, use the non-converting APIs (for example, jdeFprintf()).
