Hi,

I am pasting my script below. This will randomly(?!) display an alphabet on the terminal.

Now i want to enhance this script with the following 2 feature

1). the script should take LINES and COLUMN variable from the shell variable $LINES & $COLUMNS

2). When the user presses the character which is displayed on the screen,the character should get vanished and the next character should start displaying from line 1.

can somebody help me out in this.

Thanks

Sridhar

Is this a schoolwork (the two "features" would sound a lot like that)? If so, say it, and don't expect ready answers..

And if it's not, pardon me.
