Re: WTO Question
Left hand/right hand? 33.1.4 Input Register Information Before issuing the WTO macro, the caller does not have to place any information into any register unless using it in register notation for a particular parameter, or using it as a base register. 33.1.5 Output Register Information When control returns to the caller, the general purpose registers (GPRs) contain: Register Contents 0 Used as a work register by the system. 1 Message identification number if the macro completed normally. You can use this number to delete the message when it is no longer needed. If you are using the CONNECT parameter to connect WTO messages, store this value in the 4-byte CONNECT field and set register 0 to zero before issuing the next WTO. Otherwise, register 1 is used as a work register by the system. 2-13 Unchanged. 14 Used as a work register by the system. 15 Return code.
