[Scilab-users] Cannot understand scilex behavior when piping

[Antoine Monmayrant]

Well,

I am not sure I can test your stuff.
When I manually feed scilab-adv-cli with your code, I get the following 
error when trying to open Edit/Axes Prop... :


--> Undefined variable: TCL_EvalStr

at line    44 of function ged ( 
/home/myhome/softs/scilab-6.0.0-alpha-1/share/scilab/modules/graphics/macros/ged.sci 
line 52 )

Is scilab-adv-cli really the equivalent?
Or are all the non-cli things deactivated?

Antoine
