Thanks to all those who offered suggestions. It appears that indeed this is the nature of SQL*Plus. Jack Van Zanen's suggestion...
is the only way to do what I want but I was hoping I could achieve what I was after without this kind of manipulation, clearly it isn't possible. I appreciate the replies.

Agreed, this has nothing to do with SQL. SQL*Plus reports results in columns - that's the way it's built and you can't turn it off by changing settings. "SET COLSEP ," merely changes the character between columns from a single space to a single comma, it's not going to collapse each row into a comma-separated list. You have to do that manually.
btw those CHAR(1) columns are asking for trouble. I would make them VARCHAR2(1). You are not supposed to actually use CHAR, it's there to look good on ANSI compatibility checklists.

Actually, this does not appear to be a "SQL" question, nearly so much as a SQL*Plus question. Unless I am completely mising something, anyway.
SQL*Plus is trying to do you a favour, and format your output "nicely" in human readable columns. There is nothing wrong with your data, nor with your query -- attempts to use INSTR and SUBSTR to remove the trailing blanks from your data are doomed to failure. Because there are no blanks. Remember, SQL*Plus is really -- as much as anything -- a report writing tool.
Sadly, I don't have the answer right at my fingertips, but the prior suggestion of COLSEP was probably on the right track (assuming that it is not, in fact, the correct answer). A few minutes with the SQL*Plus documentation ought to get you what you need.

Does not work, because there's no space in the data, INSTR(FOO,' ') returns zero and so SUBSTR(foo,0,0) returns an empty string. > Is there any way to achieve the desired result in vanilla SQL*Plus short of the following (which looks like line noise), or resorting to PL/SQL or some other language (Perl, Java, ...)?
