Syntax
Arguments
Example

Syntax

CALL MSMQBEGINTRANS(transObj, rc);

Arguments

transObj

Numeric, output

Returns the transaction object.

rc

Numeric, output

Provides the return code from the CALL routine. If an error occurs, then the return code is nonzero. A return code of -1 reflects a SAS internal error. Otherwise, it represents an MSMQ error code. You can use the SAS function SYSMSG() to obtain a textual description of the return code.

Example

This example creates a transaction object.

length msg $ 200;
transobj=0;
rc=0;
CALL MSMQBEGINTRANS(transobj, rc);
if rc ^= 0 then do;
   put 'MSMQBeginTrans: failed';
   msg = sysmsg();
   put msg;
end;
else put 'MSMQBeginTrans: succeeded';
