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.
