* History:
*
* 16-Jul-1998 (Hans B Pufal)
* Started.
*
* 16-Jul-1998 (John P Price)
* Seperated commands into individual files.
*
* 19-Jul-1998 (Hans B Pufal)
* Implementation of FOR.
*
* 27-Jul-1998 (John P Price )
* Added config.h include.
*
* 20-Jan-1999 (Eric Kohl)
* Unicode and redirection safe!
*
* 01-Sep-1999 (Eric Kohl)
* Added help text.
*
* 23-Feb-2001 (Carl Nettelblad )
* Implemented preservation of echo flag. Some other for related
* code in other files fixed, too.
*
* 28-Apr-2005 (Magnus Olsen) )
* Remove all hardcode string to En.rc

* Perform FOR command.
*
* First check syntax is correct : FOR %v IN ( ) DO
* v must be alphabetic, must not be empty.
*
* If all is correct build a new bcontext structure which preserves
* the necessary information so that readbatchline can expand
* each the command prototype for each list element.
*
* You might look on a FOR as being a called batch file with one line
* per list element.
