    [ https://issues.apache.org/jira/browse/VELOCITY-542?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16650467#comment-16650467 ] 

Claude Brisson commented on VELOCITY-542:
-----------------------------------------

FYI, the behavior with null macro arguments is now configurable via the velocimacro.preserve.arguments.literals configuration value, see [VELOCITY-904|https://issues.apache.org/jira/browse/VELOCITY-904].

>    Affects Versions: 1.5

> The following example:
> #set($thisCampNumber = 10)
> #set($nextCampNumber = $thisCampNumber+1)
> #set($previousCampNumber = $thisCampNumber-1)
> #set($previousCampNumberB = $thisCampNumber - 1)
> 1: $thisCampNumber<br>
> 2: $nextCampNumber<br>
> 3: $previousCampNumber<br>
> 4: $previousCampNumberB<br>
> produces this result
> 1: 10
> 2: 11
> 3: $previousCampNumber
> 4: 9
> Note that using a minus sign in a #set statement does not work if there are no spaces around it.  (however, the same is not true for +).
