Looks like it is not installed on my system. :-(

Of-course not. In principal I like them. :-D

Just copied from other files. I will delve into it.

OK.

I am making it for FaceBook, so I have to set it to 404 pixels.

I am a programmer, not a graphical person, but willing to learn. ;-)
I'll take this into account also.

It is still good to know when I do need it. :-D

I already am working with count (after putting the strings on the
stack). My next step was to go to work with an array. First of all I
then could go through it twice. First to check the width of the
strings and then the printing. Secondly I want to work with input from
a file. But let first learn to walk before I start running.

By the way, string width is linear to the font size? So when the
longest string is to long (or short) I can change the font size
without checking again.

That is because I was popping things of the stack. I already changed
that by putting them reversed on the stack. At the moment I am working
with an array the problem is gone.

Nice touch. I'll incorporate it.

It does. Thanks for the help and also for the compliment. Both do not
hurt.
