Abstract: DISCLOSED IS A DATA PROCESSING SYSTEM WHICH UPON DETECTION OF ERROR DURING THE EXECUTION OF AN INSTRUCTION RETRIES THE INSTRUCTION. UPON DETECTION OF ERROR, THE DATA PROCESSING SYSTEM ENTERS A RETRY MODE OF OPERATION AND RETRYS THE PREVIOSULY UNSUCCESSFULLY COMPLETED INSTRUCTION STARTING WITH THE LAST SUCCESSFULLY COMPLETED STEP AS INDICATED BY A COUNTER WHICH COUNTS THE NUMBER OF SUCCESSFULLY COMPLETED STEPS. UPON ENTERING THE RETRY MODE, THE COUNT IN THE RETRY COUNTER IS USED TO UPDATE THE ADDRESSES AND OPERAND LENGTH INDICATORS THEREBY MODIFYING THE RETRY EXECUTION AND TAKING ADVANTAGE OF PREVISOULY ERROR-FREE CALCULATIONS.
