PCFHeader (MQCFH)

This is the programmable command format (PCF) header, defining the PCF parameters that follow the MQEPH structure. This enables you to follow the PCF message data with other headers.

The PCF header is initially defined with the following values:

Table 1. Initial values of fields in MQCFH
Field name	Name of constant	Value of constant
Type	MQCFT_NONE	0
StrucLength	MQCFH_STRUC_LENGTH	36
Version	MQCFH_VERSION_3	3
StrucLength	None	0
Command	MQCMD_NONE	0
MsgSeqNumber	None	1
Control	MQCFC_LAST	1
CompCode	MQCC_OK	0
Reason	MQRC_NONE	0
ParameterCount	None	0

The application must change the Type from MQCFT_NONE to a valid structure type for the use it is making of the embedded PCF header.
