5.2.7 exportto

Syntax:
exportto( package_name , name );
exportto( package_name , list_of_names );
Purpose:
transfers an identifier in the current package into the one specified by package_name. package_name can be Current, Top or any other identifier of type package.

Note:
Objects defined in a ring are not automatically exported when exporting the ring.

Warning:
The identifier is transferred to the other package. It does no longer exist in the current package. If the identifier should only be copied, importfrom should be used instead.

Example:

 
proc p1
{
  int i,j;
  exportto(Current,i);
  intmat m;
  listvar(Current);
  exportto(Top,m);
}
p1();
