HOME device question

[Kevin Toppenberg]

I am stepping through code that compares a KIDS file to the local system.  As part of this, it asks for the output device via a call to ^%ZIS (standard device call).  The default is HOME, and this unfortunately has a page width of 80 characters. How do I change this?

At this link: https://hardhats.org/kernel/html/zis.html, it shows that HOME can be a default value.  

And output variable IO(0) is set to the home device.  When I check this, I get as below, showing my home device is "/dev/pts/1"

yottadb>ZWR IO
IO="/dev/pts/1"
IO(0)="/dev/pts/1"
IO(1,"/dev/pts/1")=""
IO("HOME")="50^/dev/pts/1"
IO("IP")="192.168.1.182"
IO("ZIO")="/dev/pts/1"

I am a little hazy on the overlap of DEVICES, which can have defined TERMINAL TYPEs.  And I would think that my HOME device, would be the device that I have logged in with.  That doesn't seem to be the case, because the display I log in with has page width (IOM) of 120, not 80 chars.

The long and the short is, how do a change the default page width of the HOME device to be wider?

Thanks

Kevin

There is a DEVICE or DEVICES file, I wonder if there is anything in there to help

Inquire into the DEVICE (#3.5) file for `50 and note the SUBTYPE, edit the TERMINAL TYPE for that subtype and change the right margin to 132

Thanks for this reply

Above is my original records.  Below is what I changed it to.  This SUBTYPE is the same one I usually log in with.   So I'll just use that, with its right margin as I would like, rather than edit C-VT102

If you answer the Device: HOME //

with HOME;132;999

VistA will use the HOME device with 132 columns and 999 lines per page
