Why do people put ";" in do {}, or "," in data fields, at the beginning of the line? -- It reflects the parse tree better by putting the combining operators (e.g. ';' and ',') at the left and their operands (or combined subtrees) indented to the right. IOW, this formating style rotates

For example: * s1 * s2 is easier to read than: s1 s2 because the reader knows that * begins an item and he only has to search a given column for the beginning of the next item. However, some people object to this style because it requires too much vertical space as compared to: ( a1, a2 ) HTH -regards, Larry
