MEMLINES( ) Function

Returns the number of lines in a memo field.

MEMLINES(MemoFieldName)

Return Values

Numeric

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.

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( ) 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.

GOTO 2
SCAN NEXT 3
   gnMemoSize = MEMLINES(notes)
   IF gnMemoSize = 0
      STORE .T. TO glNoMemo
      STORE 1 TO gnMemoSize
   ELSE
      STORE .F. TO glNoMemo
   ENDIF
   IF gnLine + gnMemoSize > 65
      EJECT
      gnLine = 1
   ENDIF
   @ gnLine,2 SAY 'Last Name: '+ last_name
   gnLine = gnLine +1
   @ gnLine ,2 SAY 'Notes: ' 
   ?? IIF(glNoMemo, 'No notes ',notes)
   gnLine = gnLine + gnMemoSize + 2
   IF gnLine > 24
