AR(0) on the right side will show contents of Alet in r0 If you read the manual, starting with the perhaps most obvious one, TSO/E Command Reference, which describes TEST and its subcommands, you will find many references suggesting you also read TSO/E Programming Guide. I probably wouldn't have started with the Programming Guide, but the pointers to it are obvious in the other book, and presumably one who is testing programs is writing them, so it might be argured that it's not a totally unexpected place to find information. If you read the TSO/E Programming Guide, you'll find it has sections about using TEST, and in one of them you find the syntax for all those TEST subcommands that let you specify addresses. And if you understand the TEST subcommands such as LIST, you know that it is of the form "LIST address" and even if you're listing a register, such as register 0, when you use "LIST 0R" the "0R" is an address as far as the LIST command is concerned. Given that you know how to list a general register (0R), if you look in the Programming Guide you can find how to list a floating-point register (0E or 0D), or even how to list an access register. So that's the book I'd suggest you read, and here's a link to the section on specifying addresses: http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/ikj4b640/3.5.5?SHELF=all13be9&DT=20100709161215 There's no need to "try" things such as "L 0. AR(0)" when you can just look up the right way to do it. You might even be able to simply guess the right syntax for listing an access register, from what I've said above, but the key point is that you're trying to list a register, and there is a common syntax for listing any kind of register. So when you want to list an access register you should be looking for something similar to how you'd list any other kind of register, and it will be a decimal register number followed by a character suffix, as the first operand of LIST. -- Walt ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
