I'm not sure you're getting the correct result if calling mline() with _mline and n>1. _mline is updated on every call, and contains the offset of the last byte retrieved during the last call (which would coincide with the beginning of the next line). Next call, if _mline is included as the offset parameter, starts from that last offset - and your second parameter is the ordinal number of the line starting from that point, so it would count lines from there. Basically, you're getting the 1st, 3rd, 6th,10th, 15th line etc. Including _mline is much faster (because Fox doesn't have to calculate the position of the line you asked for), but if you want to get ALL the lines, call it with

mLINE(MNOMBRE,1,_MLINE)
