If you're asking about compound indexes as in a CDX file, do this:
index on field1 tag tag1
index on field2 tag tag2
index on field3 tag tag3
If your asking about a compound index expression, assuming all 3 fields are of type character you could do:
index on field1 + field2 + field3 tag tag123 or
index on field1 + field2 + field3 to indxfile
