GO DEBUG subcommand Use the GO subcommand to exit from the debug environment and begin program execution. The format of the GO subcommand is: +----------+------------------------------------------------------------------+ | GO | [symbol|hexloc] | +----------+------------------------------------------------------------------+ where: symbol is the symbolic name assigned to the storage location where you want execution to begin. hexloc is the hexadecimal location, in relation to the current origin, where you want execution to begin. Usage Notes: 1. When you issue the GO subcommand, the general registers, CAW (channel address word), and CSW (channel status word) are restored either to their contents upon entering the debug environment, or, if they have been modified, to their modified contents. Then the old PSW is loaded and becomes the current PSW. Execution begins at the instruction address contained in bits 40-63 of the PSW. 2. When you specify symbol or hexloc with the GO subcommand, the specified address replaces the instruction address in the old PSW, so execution will begin at that address. If you entered the debug environment with the DEBUG command, you must specify an address with the GO subcommand. 3. The address you specify must be within your virtual machine and it must contain a valid operation code.
