With the program P1B2PREQ, we can send a file with a PI99 field with a length of 48 (Statement A48).
unfortunately , in the Journal, the field "USDF ->" has a length of 41. We can use PF11 to see the other characters but it is not very practical.
The field after "USDF ->" is the field BLKSZ. There is room after this field.
Why not shift the BLKSZ 7 characters on the right ? So there will be room for all the first 48 characters of "USDF ->".
