Hey all

Some time ago I think Fabio Lunardon demonstrated using fsize to check for the presence of a field. What thread was that? I can't find it though I looked.

Considering the need to manage SET COMPATIBLE for a UDF to use FSIZE I can't see it being the fastest way.

I have used a UDF based on TYPE() and it is faster than a UDF using FSIZE that also handles setting and resetting SET COMPATIBLE. I think I found FIELD() is faster.

There is another consideration. Using a UDF can be slow, so using an idea that is in my FoxPro Advisor article: http://advisor.com/doc/17440, the command that can detect a field with the fewest external dependencies could be directly injected into code. It seems the easiest and fastest is to use FIELD().

Did FIELD() always accept the fieldname and alias?
