I'm using a point/dot as a "null" value in my own rexx programs or functions 
and do not have any problems with it. 
This is used when the args to the rexx is not/can't be comma delimited in a 
rexx way.
E g:   Call EXAMPLE 'A . . D' 

So Your example maybe could be:  thingn(option1,'.')



Regards,
Thomas Berg

I should have noted that NULL, NONE, et al. are valid, so we can't really use 
any of them. Something like *NONE would work, but is also pretty ugly.
