VLSCMP: Specifies that short variable-length compare fields are padded with binary zeros.

Can I use nosolrf instead of solrf for SORTOUT LRECL?

If you want DFSORT to use the input length for the SORTOUT LRECL even when INREC or OUTREC is present, you can use NOSOLRF, but be aware that this can cause padding or truncation of the reformatted records, or termination. CAOUTREC can be used instead of SOLRF.
