Sending PCI specification - Key = '0047'

DALPCIS specifies the relationship of PCIs during sending operations to the allocation and freeing of buffers. When you code DALPCIS, # and LEN must be one, and PARM contains one of the following values:

X'01'

A PCI and no new buffer allocated (R)

X'04'

No PCIs (N)

X'10'

A PCI and a new buffer allocated (A)

X'40'

A PCI, new buffer allocated, and first buffer remains allocated (X)

Example: To specify no PCIs during sending operations, code:

KEY    #      LEN    PARM
0047   0001   0001   04
