DALMEG specifies a block size in megabytes. (1 megabyte = 1024 kilobytes.) It is mutually exclusive with the kilobyte and megabyte block size type keys (DALKILO, DALGIG), and is used to specify that the block size requested via DALBLKSZ is in megabytes. When you specify DALMEG, the maximum PARM value for DALBLKSZ is '0080'. When you code DALMEG, # must be zero, and you do not specify LEN and PARM.
