To start the trace function, press the Cmd key, then the C key, then enterthe following:Tnsswhere:Tns= The uppercase letter T to select the trace function.= O-To display trace output on the screan only.4-To write trace output to data set 15.= 01-To trace branching instructions only.02-To trace decimal arithmetic instructions only.03-To trace branching instructions and decimal instructions.04-To trace nonbranching instructions only.05-To trace all instructions except binary and decimal.06-To trace nonbranching instructions and decimal instructions.07-To trace all instructions except binary instructions.OS-To trace binary instructions.09-To trace branching instructions and binary instructions.10-To trace decimal and binary instructions.11-To trace decimal instructions, binary instructions, and branchinginstructions.12-To trace binary instructions and nonbranching instructions.13-To trace all instructions except decimal instructions.14-To trace binary instructions, decimal instructions, and nonbranchinginstructions.15-To trace all instructions.Note: To cancel trace output to data set 15, specify trace output to the displayscreen only (option TOss). This puts the trace program in address-stop mode.Then press the uppercase letter C to cancel address-stop mode. This does notclose data set 15.ADDRESS-STOP MODEAddress-stop mode causes the 5280 to stop executing program instructions whenit reaches the instruction at a specified address. To start address-stop mode or alterthe address-stop, enter the following:A@@@@where:@@@@ =The address of the instruction at which to stop, relative to the start of thethe partition.When the 5280 stops program execution at the selected address, -the followingfunctions can be requested.Diagnostic Aids 315
