Problems with QRCVDTAQ

Hi,
When I execute the a call to QRCVDTAQ (an excerpt shown):


decimal(5,0) lRet = 0.0d,

lBuf = lBuffer,

waitTime = 0.0d;

decimal(3,0) lSenderId = sizeof(senderId),

keyLen = 4.0d;

char keyData[4];

error_code_t ec;



QRCVDTAQ(queueName,

queueLib,

&lRet,

buffer,

waitTime,

" ",

0.0d,

&keyData,

lSenderId,

(char *) &senderId,

removeMsg,

lBuf,

&ec);

The program crashes – no error returned it just abends somewhere in the call. However, if I cut the code off prior to the “ “ (the key comparison operator) the call works. If I cut it off prior to the lSenderId then it crashes. I only need that key stuff there as a placeholder so I can retrieve the sender information. I’ve tried so many different permutations but I cannot get past this. I may have been staring at it so much that I am missing something obvious so I’d welcome any suggestions.
This is under i7.3.
