Leaving "else" expression empty in if statement

[taylorbray]

I have 4 different "if" statements that change a single variable based on a single condition, but I only want the variable changed when there is a positive result from the conditional statement. Is there a way to leave the expression after else blank? Or might the switch statement be useful for this application?

Snippet of code for reference.

if countxd > 0 {
short=yes;
} else {
short=no;
}

Thanks in advance,
Taylor

stop posting snippets.
post the whole code.

you say you have 4 conditions, then show an example of 2?

maybe check for negative first, then check several positive ranges?

def x = if a < 0 then 0
else if a < 10 then 1
else if a < 30 then 2
else 3;
