A "delimited string" in this block is delimited by any printable character on both sides (except a character with code less than 32). (The above list of pattern codes maybe it isn't explained very well; hopefully someone else know how to improve it better.) After the instructions for a % block is executed, there should be only one or zero items on the stack. If none, then this one is ignored; if there is one, then it is added to the accumulation. For all three kinds, if only one value is given it can use that even if it is not a number. After the instructions for a : block is executed, the possible cases are: * The stack is empty, or contains only a mark: The result is null. * The stack contains only a number: The result is that number. It will be treated as signed or unsigned according to the column type. * The stack contains one or more items, of which the first (bottom) one is a string: Concatenates all of them together, which can be strings, numbers (treated as unsigned), or classes. All formatting codes of strings will be stripped, so that the result will be a unformatted string. |
