Marcin, I'm going to make a guess that you are writing this in RPG. Since you state that the incoming data is a fixed format defined by a format file with a leading format id, you would include each format as an externally defined data structure and within your program, once you determine the format id, do a MOVE of the variable data portion of the incoming string to the proper data structure. Or, you can buy an EDI package today that already does this or spend the next year or so trying to get it right. That year or so has the cost of lost opportunity above a beyond the cost of your wages, machine time, desk space, erasers, etc. Marcin Sagan wrote: > >>> "James W.
