It is a bit hard to say from the information you give. When do you get this error? Try stepping through your sources to find out when this happens.
What's in a sig? Would my posting look less if it didnot have a sig? (Free after William S.) :)

I get this error when I try to read or write a field from my dbf file. I use MyDbfField.Value and MyDbfField is type TStringField, just like TTable component in Delphi, what is wrong? The documentation about TDBF component is very poor. When I can find information about this package?

//--
{$I stdsig.inc}
//-I still can't read someones mind

I declare MyDbFField in a DataModule and I assign MyDBFField in another Unit in the poject that use the unit DataModule. Is it wrong?

Could you post some relevant pieces of code, so we could have a look? If we continue like this we have to keep guessing and that usually is no good at all. :)

Okey in the DataModule I declare:
...
    TSinInfo: TDbf;
    TSinInfoEMPRESA: TStringField;
    TSinInfoRUTA: TStringField;

...
where TSIninfo is my table and TSinInfoEMPRESA,TSinInfoRUTA  are the fields in my table. When I open the table in another unit, I do:
...
  ruta :=ExtractFilePath(ParamStr(0));
   DM.TSInInfo.FilepathFull := ruta;
   DM.TSinInfo.Tablename := 'SinInfo.dbf';
   DM.TSinInfo.Exclusive := True;
   DM.TSInInfo.Open;

....

It is Ok, but the the project crash when I do
...
    DM.TSInInfo.Insert;
    DM.TSInInfoEmpresa.Value := ENombre.Text;

...
Just in the line DM.TSInInfoEmpresa.Value := ENombre.Text; I get the error message:  "PROJECT MYPROJECT RAISED EXCEPTION CLASS 'EXTERNAL: SIGSEGV'".  I hope that somebody can help me. Thank

I knok what's wrong, I should use

TDbf1.FieldByName('MyField').AsString := 'Whatever';

Instead Of

DM.TSInInfoEmpresa.Value
