General Code Syntax Question

Question

Once in a while I come upon a situation where I need to use a
nested
if/else. Typically to first check to see if a value is null,
and, if not,
then do a proper check of the values. For instance:
dim returnValue
If myVariable is db.null value then
returnValue = X
else
if myVariable > 5 then
returnValue = X
else
returnValue = Y
end if
end if
I find that ugly, due to having to repeat 'X' twice, which
can be a pain if
X is actually a reall long string or the like.
What's a better way to handle that?
I've used this on occasion:
dim returnValue = X
If myVariable is db.null value then
nothing
else
if myVariable > 5 then
nothing
else
returnValue = Y
end if
end if
Which seems a tad less messy.
Thoughts?

Answer 1

dim returnValue = X
IF myVariable NOT null THEN
IF myVariable <= 5 THEN
returnValue = Y
END IF
END IF
