combine Scheme and TUI possible in Fluent Journal?

Qian Zhen

Is it possible to use TUI (text user interface) grammar in Scheme? such as (in this journal, if u<10, KE turbulent model will be adopted, otherwise just display u):

;------------------------------------------------- (define u 5) (if (< u 10)

(/define/models/viscous/ke-standard)

(display u)

) ;-------------------------------------------------

but Fluent refused to do it, give output as "Error: eval: unbound variable Error Object: /define/models/viscous/ke-standard"

I know is is possible to use (cx-gui-do ....) to execute GUI command Is there any way to execute TUI in Scheme?

thanks a lot
