Suppose a proc step has a DD statement like
//ABC DD DSN=TEST.FILE1,DISP=SHR
DSN=TEST.FILE2,DISP=SHR
and the above DD name is overridden from the JCL as given
below
//procstepname.ABC DD DSN=TEST.FILE3 - Will the DD
statement now have just TEST.FILE3 or it will be TEST.FILE3
and TEST.FILE2?
Suppose if it is overridden twice like
//procstepname.ABC DD DSN=TEST.FILE3
//procstepname.ABC DD DSN=TEST.FILE4
Will this give a JCL error? If not, what will be final
output?

Question 1:
TEST.FILE3 and TEST.FILE2
Note:
If you just want TEST.FILE3 you must nullify the TEST.FILE1
and TEST.FILE2 concatenation as in:
//procstepname.ABC DD DSN=TEST.FILE3.DISP=SHR
// DD DSN=NULLFILE
Question 2:
TEST.FILE3 and TEST.FILE2, the second override will be
ignored
