resizing system variable [message #82579]

My apologies if this has been answered elsewhere, or if the answer is
obvious, but...

I use defsysv to define an array. Later on, I want to set that system
variable equal to an array of another size, but I get an error message
that the system variable and second array are conflicting data
structures:

pro one
defsysv,'!var',fltarr(10)
!var= findgen(20) ;this gives an error.
end

I've tried setting !var=!null, but I get an error message to the
effect the !null is undefined. Which is true, in a way, of course.

Does anyone know of a fix for this? Could I define !var as a pointer,
which could point at one or another array?

Thanks,

Mark
