Secondary buffer reserve specification - Key = '004B'

DALRSRVS specifies the number of bytes to be reserved in buffers other than the first for insertion of data by the DATETIME and SEQUENCE macros. The UCS (DALUCS) key is mutually exclusive with DALRSRVS. 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 secondary buffers, code:

KEY    #      LEN    PARM
004B   0001   0001   08
