if  x in <->
;if x = - i want do empty code.

You can quote it:

Code:

macro up x {
if `x eq '-'
        display 'skip me',10
else
        display 'use me',10
end if
}

This construction working?

Code:

macro up x {
if `x eq '-'
        display 'skip me',10
If `x eq '&' 
        display 'next', 10
else
        display 'use me',10
end if
}
