[racket] want to pass argument via terminal in linux

You'll want to look at dynamic-require for this. Require forms do not accept arbitrary Racket expressions because they are used at compile time.

Thanks a lot!! it works but small problem: 
--------------------------------------- 
in command line: 
racket program.rkt test-case.rkt 
------------------------------------------ 



in program.rkt: 
(define case (current-command-line-arguments)) 
(display case) 
(require case) 


------------------------------------------ 


display works fine, but require 

gets this error: 
......................................... 
case: standard-module-name-resolver: collection not found 
collection: "case" 
in collection directories: 
C:\Users\boshra14\AppData\Roaming\Racket\5.3.1\collects 
C:\Program Files\Racket\collects in: case 
..........................................

I recommend that you keep the Racket list in CC, so that you don't 
depend on just one person to help resolve your questions. 


It would be helpful to show what your programs look like now. I 
expected using 'provide' and 'require' to work to refer to variables 
in other modules. The Guide introduces them here: 

http://docs.racket-lang.org/guide/module-basics.html 

If you can show us what you're doing, we may be able to identify where 
the problem is coming from.
