Re: DDS Display attributes

It does fail gracefully. if it fact fails. The user just will not see the DSPATR you intended for them to see. If your shop is all Client Access and the hardware is newer than.. maybe the early 90s? (I am not sure of the year) then it would surprise me if using the hex codes will do you in. The problem of course is the 40-char blivet. And, of course the problem of user input if the field is input-capable.

I have used this technique for... gosh... 10+ years and never had an issue. An example of how I use it is the top image at

http://www.martinvt.com/Code_Samples/FAQ/faq.html

to give my subfile line a different color to show subfile dividing points.

Thanks for the info Doug
I have done a little analysis, and right now I'm leaning on NOT doing this.
Testing this on ALL the devices & emulators in our shop would be a royal
pain, and knowing my luck, the last one tested would show that it wouldn't
work.
It was SUCH a good idea, but alas, as with all my ideas, they always look
good on paper.

Alan,

Thanks for taking the time for writing such a comprehensive response

I shall certainly investigate what I originally had planned on doing.

If you really are going to do that, just be aware you need to test it on

all

the devices / emulators you use in your shop. In theory you should also
first use DSM to verify the device reports that it supports WEA orders.

I

also looked it up and I remember incorrectly what WEA stands for -- it is
Write Extended Attribute. Here is a link to the page in the 5494

Functions

Reference:

http://publib.boulder.ibm.com/cgi-bin/bookmgr/BOOKS/CO2E2001/15.6.
11?DT=19950629163252

but you'll want to prefix that with a Set Buffer Address order (SBA) to

set

the row and col position to be modified. You can change not only the
highlight / reverse image / underline status, but the color of each
individual character as well.

I remembered there was also an article once I how to do this, so I

searched

for it. You may find this helpful:

I also remember another article which I'm not finding online -- I think

it

was in whatever iSeriesNetwork was called at the time in the 90's, and

was

titled something like "Colour Me RPG". But searching their archives for
various phrases which should have been in the article, I'm not finding it
now.
