1. Writing a stream of data to an EditText box
Thanks to Robert Craig for his comments about C programs displaying on full
screen.
I found a solution amongst the Troubleshoot section of the Manual.
Alt+Enter toggles between full screen and a window - simple!
Now for my latest problems:
How do you write a stream of data (atoms or integers) to an EditText box or
similar
control in Windows IDE (judith's).
In a simple example I want to write the results of a for...do loop
so that all the output is visible on the same line.
for x=1 to 10 do
setText(EditText1,x)
end for
Hoped for output would be 1 2 3 4 5 6 ... 10
I have also tried all permutations of wPuts(), wPrintf(), and wPrint() and the
best
I can achieve is for each number to overwrite the previous, ending up with 10.
I have also tried getScrollPos() and setScrollPos() to try to move the text
along a bit,
but no go. I suspect that EditText boxes do not have a cursor location facility.
What is the solution?
Second question.
In the progressbar.exw demo bundled with W32lib the output to the progress bar
is
setText(Gauge, sprintf("%d%% (%d)", sequence etc...
Can someone explain the format string? %d I'm familliar with, but can't figure
out what the rest does,
particularily the (%d). It doesn't seem necessary as a simple "%d" works fine.
Again, any help gratefully received.

When you call setText(), you're literally SETTING the text in the box, that's
it: whatever is there is replaced. You want to append text to the box, so use
appendText().
And get/setScrollPos() has no affect on a text box. See get/setIndex() for
cursor positioning.

Special characters for printf() (and sprintf) are escaped by '%' and nothing
more. The parentheses will display as-is. The double '%' prints a literal '%' in
the string. That formatting would output something like this:
printf(1, "%d%% (%d)", {52, 37})
-- prints "52% (37)"

sequence text text = {}
for x=1 to 10 do
text&= sprintf("%d ",{x}) -- note space so number won't run together
end for
-- set the edittext1 with the text sequence.
setText(EditText1,text)
