Hi,
When we want to setup a couple of get message options, the code in the sample programs I got is as follows.
Compute MQGMO-Options = MQGMO_ACCEPT_TRUNC_MSGS +
MQGMO_WAIT
Add MQGMO_CONVERT to MQGMO_OPTIONS
Add MQGMO_SYNCPOINT to MQGMO_OPTIONS
I found in IBM manuals that all the MQGMO options are the integer numbers, which are powers or 2. ( like 2, 4, 8, 16 etc.,)
I am assuming that by adding any of these numbers, we should only get a unique number, and MQ should be able to resolve that unique number into a combination of options
But, the MQGMO_CONVERT is always added separately in all my sample programs. Can any one please explain the reason why MQGMO_CONVERT is added separately. Essentially, COMPUTE & ADD verbs should work similarly. |

i think it's not integer, it's binary. if you look at CMQV and CMQGMOV copybooks in %SYS%.MQM.SCSQCOBC you will get some idea.
| Code: |
MQGMO-CONVERT PIC S9(9) BINARY VALUE 16384.
|
| Code: |
** MQGMO structure
10 MQGMO.
** Structure identifier
15 MQGMO-STRUCID PIC X(4) VALUE 'GMO '.
** Structure version number
15 MQGMO-VERSION PIC S9(9) BINARY VALUE 1.
** Options that control the action of MQGET
15 MQGMO-OPTIONS PIC S9(9) BINARY VALUE 0.
** Wait interval
15 MQGMO-WAITINTERVAL PIC S9(9) BINARY VALUE 0.
** Pointer to signal
15 MQGMO-SIGNAL1 POINTER VALUE NULL.
** Signal identifier
15 MQGMO-SIGNAL2 PIC S9(9) BINARY VALUE 0.

and it shouldn't matter whether we add CONVERT separately or at one time. Effectively it is not like adding (mathematically), it's like adding options in a single basket (switching on options) before doing MQGET. |
