Hello James, >From your last sentence, I guess you're looking at doing this in a MB(?) program rather than with Pro's user interface.
As a rule, I say away from using "target" related commands unless I want the user to be involve (typically with setting the target). For programmatical object processing, it's much better to use overlap() and erase() to implement the "Erase..." and "Erase Outside..." functionality. This is especially true when just updating an object with no need to change attributes since you can just do an SQL update on the obj field. Using the target commands nearly always involves messing around with building statement into strings and doing a "run command" - I avoid this wherever I can.

This part works fine, it is when using the data clause that I have a query. Is it possible to tell Mapbasic that you want all of the columns to be the same as the original table (i.e. to not equal a value, a proportion or be assigned blank), or can you / how do you set up the data clause so that the intersect statement can deal with different tables that don't always have the same number of column and names (i.e. the column names are not hardcoded). I have tried to add For loops at various places but this does not work. Regards James Stott This Electronic Transmission is intended only for the attention of the addressee.
