1. Something weird
--------------3DBBF0EFDD7E3C1219761B7E
I was writing this simple program that had the user input a word, and
then the program searched a list of 200 words to find a match. It then
printed out on screen whether the word (or part of the word) was found
or not, what number the word was in the sequence, etc. Simple stuff,
yes, not meant for use other to see how match() worked, and how fast.
Anyway, for some reason when the cursor got to the bottom of the screen,
replies from the program tacked an extra line feed on. When I took the
"\n" out of the beginning of my output, the program still tacked a LF
on, but not a carriage return. Example:
prog output user input output
What is the word? stop
That was word# 175.
So I put in a get_position() to take care of it. If the row was 25,
then the program did not output a LF, but it did put in a CR, or ASCII
13.
All of this is no big deal, but I ask, why would Euphoria do this? I
put a trace(1) in and saw nothing in my code that would cause this.
Thanks!!

From LIBRARY.DOC, gets() routine:
After reading a line of text from the keyboard, you should
normally output a \n character, e.g. puts(1, '\n'), before
printing something. Only on the last line of the screen does the
operating system automatically scroll the screen and advance to
the next line.
It's a quirky thing about DOS. Euphoria is not
doing anything different at the bottom of the screen.
Several people have asked about this over the years.
Use get_position() and position() if you need better control.
