If you look at cmqc.h, you will see the following:
typedef unsigned char MQBYTE;
typedef MQBYTE MQPOINTER PMQBYTE;
typedef PMQBYTE MQPOINTER PPMQBYTE;
typedef MQBYTE MQBYTE8[8];
typedef MQBYTE8 MQPOINTER PMQBYTE8;
typedef MQBYTE MQBYTE16[16];
typedef MQBYTE16 MQPOINTER PMQBYTE16;
typedef MQBYTE MQBYTE24[24];
typedef MQBYTE24 MQPOINTER PMQBYTE24;

I am not sure why you want to convert string to MQBYTE24. Please fill me in on that.
My advice is you stick with MQBYTE24 if you want to let MQ decide or generate the msgid and correlid. Changing that to string, would only put you into trouble - if you are unlucky. Check out a topic on this problem with msgid and correlid after an upgrade.

| I'll also add that you can get into trouble with treating the message and correlation id's as strings if you are moving around platforms. These fields are not converted and will give you trouble if you try string compares between ascii and ebcdic. |
