The previous line evaluates to 'display , ' when the perl interpreter
hits it because it looks for the variables $var1 and $var2, but can't
find them, so it uses '' (the string value of undef) instead. You might
want to try:
$Cmd = 'display $var1, $var2';
Same thing for the hash you're creating... If you want to do what I
think you want to do, you need to define that hash as:
$VarValue{'$var1'} = 'val1';
$VarValue{'$var2'} = 'val2';
