help help help please

Please guys,
help me just to understand the concept of passing variables from MEL as argument of a c++ method of a MPxCommand class in a MfnPlugin

If I had register my command as "Calc" and i have the DoIt method which will receive the argument, and i want to pass it the string $text MEL variable, i see that simply write:
Calc( $text) as procedure call in mel doesn't work...

please help or just send some source code example to me via email.

thank u all

Calc ($text) will stand for MEL procedures, if you are calling a command, you should write Calc $text
