[ferret_users] define viewport

[Brockmann Patrick <Patrick.Brockmann@xxxxxx>]

Hi all,

I have encountered a bug with ferret 6.3 on x86_64 plateforms only.
A problem of precision detected within a layout script.
Simplified as the following line :

let var=0.9999999 ; def view/xlim=0,`var`/ylim=0,1 view1

It gives
yes? let var=0.9999999 ; def view/xlim=0,`var`/ylim=0,1 view1
!-> def view/xlim=0,/ylim=0,1 view1
**ERROR: command syntax: xlim=0,/ylim=0,1

It this bug corrected with 6.4 on x86_64 ?
Thanks

Patrick
