ACF/TAP supports VTAM® full
buffer trace data, but prints a maximum of 256 bytes per record.
Starting with SSP V4R8, the control parameter LONGPIU=YES can be specified,
and up to 4096 bytes of VTAM full
buffer trace data per PIU is printed. This could be 4096 bytes from
one GTF record or 4096 bytes reassembled from multiple GTF records.
