And I guess the bottom line on the original technical question is: - DISP=NEW fails if the PDS already exists (or, if you will, "may be used to make certain that the PDS does not already exist"); DISP=MOD is good either way. - DISP=NEW and MOD both fail if the member already exists but fail differently: NEW fails on the CLOSE with SB14-04 -- this can only happen if the program creates the member during execution (OPEN, PUT, CLOSE, OPEN, PUT, CLOSE) because after all the PDS must be brand new; MOD fails on the OPEN but I am not sure of the exact error.
