You need to see if the JCL that creates the JCL have things like RETPD= EXPDT=
For GDGs, you also need to list the BASE GDG and see if it has NOSCRATCH OR NOEMPTY or SCRATCH or EMPTY Normally a GDG is created with EXPDT=99000 which is Catalog control. Then when the +1 generation is created, if the Limit is reached, then the oldest version will drop off if the GDG is defined with Scratch NOEMPTY. A Limit of 14 means keep 14 versions. If you create 14 in one day, then it will cycle very quickly. If you create a GDG once per week it will last for 14 weeks. This will depend on the frequency of the creation of the GDG. A search on the IBM Website for GDG CREATION provides this link.
