<nLines> is the number of lines to be eliminated, beginning with the current record position.
If <nLines> is omitted, the current record is deleted only.
Returns
TRUE if successful, otherwise check ft_fError() for error code.
Description
This function deletes one or several lines of text from the file in the currently selected text file workarea. Text lines are delimited with a CRLF pair. The record pointer is not moved, unless the deleted lines occur at the end of the file, in which case ft_fRecno() will equal ft_fLastRe() and ft_fEOF() will be set to TRUE.
Examples
// delete the next 4 lines from a file FT_FUSE( "test.txt" )
