By default, when RJSE uploads RECFM=LSEQ datasets to the host, it uploads them as RECFM=FB datasets. To override this default, set the %LSEQRECF JCL extension keyword to specify which type of RECFM datasets to upload:

%LSEQRECF=[ V | VB | F | FB ]

Note: We strongly advise that you assign the LRECL for your local LSEQ dataset to an appropriate non-zero value. If you set the LSEQ dataset to a value of 0, RJSE generates a warning message and defaults to using a value of 80 for F and FB and 255 for V and VB which could lead to execution failures.
