I had only used found with seek. it occurred to me in the middle of the night last night that I should be able to use it with locate.
thanks dragan - for the pointers.

>>tnx Naomi - Using 'locate' how would you determine if a match was not found. I am avoiding seek because of the indexing.

>The Continue command just repeats the search using the same expression, starting from the current record. This is the old way of doing scan for (before scan was introduced in 1991), which was still useful (the cached bitmap helps to speed it up) so it's still available and will be.
