Hi Matthew, I've done a lot of CCW programming of CTC devices over the years but unfortunately for this case the vast majority of it was in a VM environment.? In a virtual machine, I could write my

Hello Matthew, Many years ago I contacted Shelby Beach who uses CTC in their DDT debug tool. In the reader part of the tool a CCW is issued using a C3 command code with a data length of 1. No sure

Hi Matthew, Being the author of the Hercules CTCE device supporting real CTCA's (even Ficon CTCA's), I must however admit that I've never written any programs performing communications using CTCA's,

Hello, I am on MVS 3.8, writing assembler code that reads from a CTC adapter. I will be running a "server" started task that should wait indefinitely for a command from the "client" program on the

Rob? Thank you for providing up to date dasd for TK4. It saves me lots of time. Laddie? I built a MVS 3.8J back in 1982 ran it under VM on a?4341 Wish?I kept a backup of the system once I

Hi Larry, In CLGLST (the list and log utility of ISPF) I found a minor bug. After quit of ISPF, you can print the log and list dataset and a job will be submiited. The userid.CARDS.Dxxx.Txxx dataset

Hi Rob, Thanks for providing your TK4ROB DASD distributions. May I suggest for the next release that you include the needed .conf file as a part of the DASD .zip file, such that merely by unzipping

Hi Larry, DUCB, DVTOC, CLGLST and RCQCAL are installed now in my system. These will be included in my next distribution of my TK4ROB volums. Cheers, Rob

Hello, I found this mentioned today on IBM-MAIN listserv: It is a 3270 emulator written in python. It supports various screen sizes and it does automation. I have not tried the automation piece but I

Fish, you found it! The folder properties are RO so when the file was created, it inherited read-only status. In fact, Hercules reported it:and I missed it. 21:42:31.914 00007548 HHC00476I 0:0344

I did that.? The third bullet shows where I take it away from Hercules. I tried with the volume mounted to MVS but ICKDSF didn't like it.? It gave me the message: ICK31049I UNITADDRESS SPECIFIED FOR

Yon don't need to shut down MVS orr VM before creating the disk, but you do need to detach it from Hercules; you can very it offline to MVS and VM, then tell hercules to detach the device, run

Thanks Jay.? I did not create the disk with alternate tracks.? Since I'm running MVS TK4- as a guest of VM/370 CE, I performed the following steps. * DETACH 344 MVS (MAINT) * VARY OFF 344 (MAINT) *

If you're going to use ICKDSF to initialize a Hercules CKD/CCKD DASD image, you need to specify the -a (alternate tracks) option to dasdinit. ICKDSF is complaining that the alternate tracks are not
