** wn_ssn(fun,frm,fld,wn,row,col,prmpt,atrib,fill,n1,n2,n3,ubuff,hlpmsg,errmsg)
**
**    int        fun - fucntion code (SET || XEQ)
**    (WIFORM)   frm - form pointer  (actual || NFRM)
**    int        fld - field # in form (actual || NFLD)
**    (WINDOWPTR) wn - window pointer
**    int        row - row in window where data input begins
**    int        col - col in window where data input begins
**    (char *) prmpt - field promt (call with NSTR for none)
**    unsigned atrib - field (not prompt) atributes 
**    char      fill - field fill character
**    (int *)     n1 - pointer to int for 1st part of ssn     
**    (int *)     n2 - pointer to int for 2nd part of ssn
**    (int *)     n3 - pointer to int for 3rd part of ssn  
**    (char *) ubuff - pointer to char array of 13 bytes for editing 
**    (char *)hlpmsg - pointer to help message (call with NSTR for none)
**    (char *)errmsg - pointer to err message (call with NSTR) for none)
**
** RETURNS:
**
**    social security number as 3 intergers and character string
**      n1, n2, n3 - contain "integer" components of ssn
**      ubuff      - contains character string of form xxx-xx-xxx
**                   ubuff's contents makes a great index.
**
**    NULL if error, else the non zero value returned from wn_input.
**
** NOTES:
**
**  FUN -   fun can only be SET for form setup, or XEQ for immediate
**          execution.  When called with SET, valid arguements for both
**          "frm" and "fld" must be specfied.  frm is the field pointer
**          returned from frmopn(), and fld is the field sequence number
**          in the form for this field.  When called with XEQ frm must
**          be NFRM and fld must NFLD.
**
**  UBUFF - Editing buffer.  Must be of sufficent size to hold the
**          data as it is entered.  Typical value is the length
**          of the mask + 2 bytes (strlen(mask)+2).
**
**          On entry, the first byte of ubuff should be 
**          a null, otherwise wn_input assumes there is valid
**          data there and will enter edit mode.  This can be 
**          handy if there is a need for prefilled but editable
**          fields.  In actual pratice, wn_input uses this
**          buffer for both initial character data entry and
**          subsequent editing.
**
**          On return, ubuff contains the actual data entered in
**          character format with fill and mask characters as
**          spaces (e.g. 046 40 4291).
**
**  No validation is performed.
**
**  Leaving the field blank returns 0 for n1, n2, and n3.
**
**  Calls wn_input to perform data entry.
