Re: Tabs in SEU

Matt,

Except that the terminal definitions were extended what, over 10 years ago?  The
5250 data stream *does* support changing the color of individual characters
without the need for intervening display attribute bytes.  All but the oldest
400's will have "enhanced" WS controllers which support this.  Look up the
"write extended attributes" data stream order in the 5494 functions reference
manual (which is where you'll find 5250 data streams these days).

Naturally, if you are using a 5251 model 11 it won't help.  But devices and
emulations which correctly implement the 5250 data stream should have handled
this 10 years ago or more.  How many telnet clients actually do?  I don't know.

SEU is already dynamically manipulating the 5250 data stream.  Or at least it
did in V1R1 when I reverse engineered how to directly insert my own display
formats into the user format file.  SEU/400 did not allow some of the options I
used under SEU/36, and I didn't want to lose functionality.  So I just wrote my
own utility to read the $SFGR from the 36 and "compile" it into the data stream
orders and record formats used by SEU/400..

It is true that IBM never enhanced DDS to use all the features they added to the
5250 data stream.  But the data stream does support it, and has for a decade...
