Joe,

In addition to Mike's suggestion, see 'More news about VFP7' in Files section. There would be a new function in VFP7.0, which gathers information about all tags in cdx.

>Is there a function that will tell if a tag exists? Input will be the character name of the tag. Returns logical.
>That would save all this looping.

>>>I think so, but I'm not sure. Check if you have ActiveColumn property in a VFP5.0 Grid. If your header caption is always the same, as the field name, you may use in Header.Click() this.parent.parent.SetOrder(this.caption). You may want to programatically create Header class and substitute Header1 with your Header class in run-time. Check Cetin's two grids class example in File section for futher details.

>>If you want to use UPPER(characterField) in your index, try this syntax in Header.Click():
>>local lcFieldName
>>lcFieldName='upper('+this.caption+')' && Caption should be exactly the same, as Field Namr
>>this.parent.parent.SetOrder(lcFieldName)

>>You can enchance it more..., but you get the idea
