David:
Here is one more for your consideration. The quick code enclosed below will
take the number of records and display it at 2 percent increments or 50
increments for the entire set, it also displays the counter as a progress
bar (very cool). You can easily change it to display at different
increments. As you will see, when you use the CHAR(219) it displays very
neatly as a bar when using the WRITE command (great for DOS) but it shows
garbled in the message bar. I have also included a quick and dirty code that
display a message (and WRITE display) for all the character codes (one at a
time) as they are dependent (I think) on the character set that you have on
your desktop (or R prompt as set in preferences). When I have a little more
time I will fine tune it to properly display a bar, in the mean time fell
free to play with it; I believe that it will take care of the screen flicker
as well with less load on resources. I believe that I will be using this
approach for my counters as it shows not only the percentage but a good
looking progress bar.
============================================================
-- QUICK CODE TO SHOWS PERCENT AND PROGRESS BAR FOR A COUNTER

SET VAR vnr INTEGER
SET VAR vinc INTEGER
SET VAR von INTEGER
SET VAR vpct INTEGER
SET VAR vnr INTEGER
-- PAUSE 2 USING 'Counting from 1 to 10000; now on 10000' AT 5 10

SET VAR vnr = .vinc
SET VAR vbar = ' '
SET VAR von = 0
SET VAR vpct = 2
WHILE von < .vno_recs THEN
SET VAR von = (.von + 1)
IF ( vnr = .von ) THEN
-- Use a character other that 62 to display a different bar style
set var vbar = ( .vbar + (CHAR(62)) )
set var vmessage = ( (CTXT(.vpct)) + ' % - ' + .vbar )
write .vmessage at 20 2
pause 4 using .vmessage
set var vpct = (.vpct + 2)
set var vnr = (.vnr + .vinc)
ENDIF
ENDWHILE
CLEAR ALL VAR
RETURN
============================================================
The following code will display a message with the different CHAR to see
which one you want to use.
============================================================
SET VAR xxx = 255
SET VAR y = 1
PAUSE 3 USING 'Counting from 1 to 10000 by 2 pct increments with .with
bargraph display' +
AT 5 10
WHILE y < .xxx THEN
set var y = .y + 1
set var z1 = (CHAR(.y))
set var z = ( (CTXT(.y)) + ' - ' +
.z1+.z1+.z1+.z1+.z1+.z1+.z1+.z1+.z1+.z1+.z1+.z1+.z1+.z1+.z1+.z1+.z1+.z1+.z1+
.z1+.z1+.z1 )

Subject: Re: PAUSE 4 and Screen Flicker
THanks to everyone who replied!
So the final answer is:
1. The initial PAUSE 3 must be EQUAL TO OR LONGER than any subsequent PAUSE
4: PAUSE 4 will not display a message any wider than the original box and
that makes sense.
2. To avoid the flicker, set it up, as in Jim's example below, to only
refresh the box once a second to avoid the WINDOWS flickering problem.
Thanks!!
