NOTE: This command is not designed for use in table fields, created with the DEFINE TABLE command.
Example
function get_state do case case substr(m_zip,1,2) = "01" m_state = "MA" case substr(m_zip,1,2) = "91" m_state = "CA" otherwise m_state = "XX" endcase show gets return .T. m_zip = space(5) m_state = space(2) @10,05 say "Enter Zip" get m_zip; valid get_state() @12,05 say "Enter State" get m_state read
