Hi Roi.

>I've seen MetaDataTables mentioned a couple times. Could someone give me hint as to what they are and what you would put in one.

"Meta data" means "data about data". In VFP, the usual context of meta data is information about table structures, such as field data types, sizes, and captions. 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).

Meta data is the key to creating generic data handling routines, since it allows you to avoid hard-coding field names, captions, and other things.
