Sorry, my mistake I realized soon after posting,
I wrote a small script to tabify/untabify in acme using Russ's tab.c
#!/bin/rc
fn addrdot { echo 'addr=dot' > /mnt/acme/$winid/ctl }
fn tabify {
        { cat /mnt/acme/$winid/xdata && addrdot } | /bin/tab -n4
        }
addrdot && tabify > /mnt/acme/$winid/data

Though it does what it supposed to do, is there a better way of doing
it (I am sure there is :))
Thanks

in general, pipe (|) is your friend. it's rare to have to interact with acme's
special files directly.

is there a reason you can't just execute "|tab -n4" ?
(perhaps i've misunderstood the script - i haven't tried it)

slight digression: i have two scripts, called a+ and a-, that
do indentation and un-indentation, as follows:

% cat /bin/a+
#!/bin/rc
if(~ $#* 0){
  * = '	'    # tab
}
sed 's☺^☺'^$1^☺
% cat /bin/a-
#!/bin/rc
if(~ $#* 0){
  * = '	'
}
sed 's☺^'^$1^'☺☺'

the short names are so that they take very little space
in an acme tag. then i have |a+ in the tag of a window,
so i can indent text simply by middle clicking it, two key strokes
and it can be changed to unindent. give it an argument and it can be
used to comment/uncomment blocks of code.

the smiley faces are to avoid doing a proper quoting job
(which i should really do in case i want to indent by '&' or something,
but i've not had the need so far)

i didn't need to mention that, but i have found them
very convenient over the years, so i did. so there.

  rog.

alternatively from acme,

	Edit s:^:	:g
or
	Edit s:^	::g

indeed, although i like the one-word nature of |a+ and |a-

that way i can have something else (e.g. a search phrase or
another Edit command) highlighted in the tag, and still single-click
on |a+ to indent without losing it. tag space is at a premium too.
