Jochen:

There's no mixing of spaces and tabs there (especially in a 'wierdo' way [Wink] ). I only entered "tabs", and the "+" represented the number of columns that the cursor moved in the editor. If you put a comment character in column 1, then tab twice to move to column 9, arbitrarily converting tabs to 4 spaces would place my text in column 10 instead of 9. (";" plus tab moves to col 5, second tab adds 4 spaces to col 9, where ";" plus two tab chars converted to 8 spaces moves 9 columns, leaving me in col 10)

Basically, tabs move to a particular column, not an arbitrary number of spaces. This is most evident when we use word processors with proportional spacing, but the concept is the same. Program editors generally use fixed width fonts, so it's easy to confuse spaces with column position.
