Mira tube un problema similar pues cuando las txt eran demasiado extensas cada cierta cantidad de datos algunos me importaban el CHR(10), debido a esto tube que cambiar las fuentes de harbour y enlazarlas como una funcion mas dentro de mis aplicaciones... esto es..

#define AppendEOF( handle ) FWRITE( handle, CHR( 26 ) )
#define AppendSep( handle, cSep ) FWRITE( handle, cSep )
