That offset is added to the address of I2REC. This a location in memory. Look at the object code in the listing to get the Base and Displacement associated with I2REC+ISTAT-IREC You will also be able to find the bit settings associated with SDLET by looking at the object code in the listings. The TM test the Location in memory with the value defined by SDLET There should be a branch or jump instruction following the TM to take the apporpriate code path depending on how the condition code is set.
