Hi Michel.

>> In an array, I have a definition of the fields of my table. So, the first row contains all the field names. When I use ASCAN to find a specific field name, it will locate the proper row. However, assuming I want to search for field name NOM and that I have another field NOMEMBER which is placed before NOM in the array, NOMEMBER will be found before NOM. How can I force ASCAN to be precise? <<

ASCAN has been enhanced in VFP 7 to allow you to do this:

*** case insensitive search searching on column 1 with EXACT set on and return the row number
lnAtPos = ASCAN( laMyArray, lcMyValue, 1, ALEN( laMyArray, 1 ), 1, 15 )
