Thanks firstly to Tom Manson and Patrick Phillips If you open a workspace the order of layers is determined from the 'map from ...' statement If you just open a load of tables in Mi it puts them in a quasi logical order (points on top lines next then polygons) as for the layer ids. the topmost layer is always 1 (say roads) the second 2 (say counties) the nth n (say the sea). if you alter the layer order via mapbasic (or in the layer control dialog) for example by moving the nth layer to the top it (the sea) assumes the layer id of 1 once the alter layer order operation is complete. friday 1 hour to a three day weekend Cheers to all Jon Jonathan Stokes GIS Analyst ******************************************************* Geoplan, 14 - 15 Regent Parade, Harrogate, North Yorkshire, HG1 5AW. tel 00 44 (0) 1423 722715 fax 00 44 (0) 1423 525 545 www.geoplan.com ******************************************************* ---------------------------------------------------------------------- To unsubscribe from this list, send e-mail to [EMAIL PROTECTED] and put "unsubscribe MAPINFO-L" in the message body, or contact [EMAIL PROTECTED]
