Hmm, I got an error message!

IDL> test = [ 'dir1/', 'directory2/', 'another_directory/' ]
IDL> print,strmid(test,0,strlen(test)-1)
% STRMID: Expression must be a scalar in this context: <LONG      Array[3]>.
% Execution halted at:  $MAIN$                 

IDL> print, !version
{ alpha OSF unix 5.2 Oct 30 1998}

Is this something new in IDL 5.3?
