This is simply a syntax correction for VFP 6 SET RELATION

There's a new IN clause in SET RELATION TO
The help file says

SET RELATION TO
  [eExpression1 INTO nWorkArea1 | cTableAlias1
  [, eExpression2 INTO nWorkArea2 | cTableAlias2 ...]
  [IN nWorkArea | cTableAlias]
  [ADDITIVE]]

Also SET RELATION TO on its own clears all relations. However it doesn't appear to work with the IN clause.

Here's the correct syntax...

SET RELATION 
  [IN nWorkArea | cTableAlias]
  TO [eExpression1 INTO nWorkArea1 | cTableAlias1
  [, eExpression2 INTO nWorkArea2 | cTableAlias2 ...]
  [ADDITIVE]]
