I have encountered this situation frequently enough that I work around it
by calling a subprogram to strip leading spaces.  I suspect that most of you
have some sort of string manipulation package that you have either 
developed or purchased.  I made sure that mine has support for removing 
leading and trailing spaces (in addition to other operations).  Then when I
want to get rid of the trailing space, I don't have to embed statements
like INTEGER'IMAGE(I)(2..INTEGER'IMAGE(I)'LAST), but can use a statement
such as REMOVE_LEADING_SPACES(FROM => INTEGER'IMAGE(I)).  This is probably
more readable, therefore it won't 'gag a maggot'.  I suspect this is the
general idea that Mr. Hoysch was suggesting when he said 'or a very simple
routine if this is too hard on the eyes.'
