Answer / nygrande
If we use the base of the GDG only, all generations will be
concatenated.
If we want to use specific GDG generations, we can code as:
//FILEA DD DSN=NAME.OF.FILE(-5),DISP=SHR
// DD DSN=NAME.OF.FILE(-2),DISP=SHR
// DD DSN=NAME.OF.FILE(-1),DISP=SHR
// DD DSN=NAME.OF.FILE(0),DISP=SHR
or use the GDG complete DSN, as G0000V00. For example:
//FILEA DD DSN=NAME.OF.FILE.G0001V00,DISP=SHR
// DD DSN=NAME.OF.FILE.G0003V00,DISP=SHR
// DD DSN=NAME.OF.FILE.G0004V00,DISP=SHR
// DD DSN=NAME.OF.FILE.G0005V00,DISP=SHR

Hi, I have a requirement File A : I have 6 records out of which 4 are same. File B: I have 8 records out of 6 records are same. The 4 records in FILEA and 6 records in FILE B are same. If we substract we will get two records, I need these two records in output file This is because to remove the duplicates from the database. Through easytrieve we can compare but for that there should not duplicates, but in my file I have duplicates. Thanks in advance!!
