_MLINE System Variable

  • 项目

Contains the memo field offset for the MLINE( ) function.

_MLINE = nNumberOfCharacters

Parameters

  • nNumberOfCharacters
    Specifies the memo field offset. For more information about the use of _MLINE and an example of its use, see MLINE( ).

Remarks

MLINE( ) returns one line of text from a memo field. MLINE( ) stores the location of its memo field offset to the _MLINE system variable. Use _MLINE as the second numeric argument in the MLINE( ) function to increase the performance of MLINE( ).

The startup default value for _MLINE is 0. Be sure to reset _MLINE to 0 before using _MLINE again with the MLINE( ) function.
