[Openroad-users] BufferText

[Andrew]

Hi Simon,

There is more work in using keypress.

BufferText is alot easier and now with using On BufferChanged its great.

ON BUFFERCHANGED comments =
declare
    fo = FieldObject;
{
    fo = Field(comments);
    tally = Length(EntryField(fo).BufferText);
}

Regards,
Andrew.
