Hi Darrel

Problem seems to be solved now.

And the solution was in the very problem itself ...passing the variable !!

I created a new variable called datatx
and then after the displaying myvar to LCD with LCDOUT,
all I did was let datatrx = myvar
then SEROUT myvar
And whammo it works :-) YAY ...!

Thanks so much for all your help !

Here's the code for reference and for anyone who might find it useful
It captures a keypress, diplays it on the LCD and send the captured keypress via SEROUT.

Kind regards
Dennis
