Hi BOb,

Off hand, I don't know of any document that describes the relationship between C data types and the declarations in VFP. In general, most parameters are either VFP strings or integers. There are, however, some data structures that require floats (floating point numbers). Return values are generally integers. You may have noted that I declared some of the return values as "SHORT". In reality, the actual return type is a BOOL (logical value). I use SHORT to indicate this for my own use. It'll return 0 if false, non-zero if true.

hth,
