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

... should I add the LOOKUP prior to making the assembly key lookup like this ?
