in reply to passing variables

As someone has no doubt already pointed out, the single quote doesn't do variable interpolation. You probably want 

system ("tremove @host:$ep");  #  WRONG -- should be \@host

instead.

Update: Sorry, as has been pointed out -- the '@' should be escaped with a leading '\'. That'll teach me to post something, then wander off to continue my work day.

    system ("tremove @host:$ep");

    That solves one problem by creating another. You've solved the problem of $ep not interpolating, but you've created the problem of @host interpolating, when the OP stated it's not intended to be a variable.

    You could use either of the following techniques:

    system( 'tremove @host:' . $ep );
system( "tremove \@host:$ep" );

    You meant to escape the @ as \@ but didn't.
