BUFSZ specification - Key = '0038'
DALBUFSZ specifies the length in bytes of each of the buffers to be used for all lines in a particular line group. It is mutually exclusive with the block size key (DALBLKSZ). When you code DALBUFSZ, # must be one, LEN must be two, and PARM contains the buffer length.
Example: To specify a buffer length of 80,
code:
KEY # LEN PARM
0038 0001 0002 00 50
