Returns the number of lines in a memo field.
MEMLINES(MemoFieldName) |
Parameters
- MemoFieldName
- Specifies the name of the memo field. If the memo field is in a table that isn't open in the current work area, preface the memo field name with the table alias and a period.
Return Value
Numeric
Remarks
The number of lines in a memo field is determined by the current value of SET MEMOWIDTH.
Example
The following example scans three records in the employee table and uses MEMLINES(В ) to determine whether or not there is data in the notes memo field and when page breaks should occur. The last_name data for the record appears, along with the notes (if there is data in the memo field) or a message indicating that there are no notes for that record.
