This parameter specifies the size of the buffer for the 3270 terminal PF key that retrieves previously input command lines. The larger the retrieve buffer, the more commands you can save for retrieval.

The minimum and default setting of RETRVBUF is 288 bytes; its maximum is 32767. The parameter setting is always rounded down to the nearest 8-byte multiple, so the largest buffer allowed is actually 32760 bytes.

Note: The retrieve buffer is a virtual storage area allocated for any full screen thread with a retrieve key set, so the cost of a large buffer is higher virtual storage usage.
