>You also do not have to use -> anymore between the table and field names. You can replace it with a .
Most of the time.Try this:
open a table
lcTableName = 'part' && table name
lcFieldName = 'partno' && field name
?part.&lcFieldName &&gives the value of part.partno
?&lcTableName.&lcFieldName &&gives an error
?&lcTableName->&lcFieldName && gives the value of part.partno
