[Newbie] output a variable on the screen

[Franco_64]

Hi all,

I'm approaching the Prime that I buy just a week ago (nice!). I'm trying to do my first program: simply a counter by 1, showing the results on the screen for 1 second.

If I use the PRINT command, Prime open a terminal and show my results in the upper left of the screen. But I want that the silly counter shows the output on the center of screen. I must use TEXTOUT? But (as I have understand) that command is used primarly to show text in a plot, and I don't need this (for now).

More in general: I've found here a list of commands with a short explanation of the meaning of each commands, but this is not so useful for programming purpose, because it's not ordered by the type of command (branches, loops, input/output...), and don't show all the help but only the first words. There is a more complete and well-structured list of commands?

Thank you, and sorry for my poor English and my newbiness :-)
