int findl(string [n])
string - string to search in.
n - 0-based index of line. Default: -1.
Returns 0-based index of first character of n-th line in string. If there are less than n+1 lines, returns -1.
If n is omitted or negative, finds next line. It works in same function only.
QM 2.3.3. Fixed bug: does not work if n omitted.
