No, it would expect to find a field called lcfieldname in your table. Instead use:

x = eval('myTable.' + lcFieldName)

>I'm in the process of trying to use a xtab query in a report. The query results are too large for a VFP report. Can I get a field value like this:
>lcFieldname = FIELD(lcFNum)

>myTable.lcFieldname = x

>Will VFP recognize the variable as a field name??
