Re^4: difficulty in matching 2 fields of a same line
in thread difficulty in matching 2 fields of a same line
Do you mean that there are lines where you want to compare fields 3 and 11, and other lines where you want to compare, say, 6 and 8, and others where fields 2 and 9 are relevant? If that's what you mean, then I suggest you provide us with the rules that decide which fields are of relevance. If this is not what you mean, then yeah, maybe you should give us an example to show what you mean.
