Hmm, That sounds interesting. Would you use it to describe all the tables in a .dbc. You would need a couple related tables though wouldn't you?

A table table, field table, index table.

Although you can get some of the meta data for a table from VFP functions (such as AFIELDS and DBGETPROP), putting all the information into a meta data table makes it easy to get at and fast (a SEEK into the meta data table to find the field of interest, and then grab the columns, such as SIZE, CAPTION, and TYPE, that contain the information you want).

In Rome, there was a poem.
About a dog, who found two bone.
He lick the one, he lick the other.
He went pyscho, he drop dead!
