First buffer reserve specification - Key = '004A'

DALRSRVF specifies the number of bytes to be reserved in the first buffer for insertion of data by the DATETIME and SEQUENCE macros. The UCS (DALUCS) key is mutually exclusive with DALRSRVF. When you code this key, # and LEN must be one, and PARM contains the number of bytes to reserve.

Example: To reserve 8 bytes in the first buffer, code:

KEY    #      LEN    PARM
004A   0001   0001   08
