** wn_gphone(fun,frm,fld,wn,row,col,prmpt,atrib,fill,acode,nnx,num,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 *) acode - pointer to int for area code (3 digits)
** (int *) nnx - pointer to int for nnx (3 digits)
** (int *) num - pointer to int for number (4 digits)
** (char *) ubuff - pointer to char array of 18 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:
**
** ACODE, NNX, and NUM via pointers.
**
** 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. 800 555 1212).
**
** No validation is performed.
**
** Leaving the field blank returns 0 for ACODE, NNX, and NUM.
**
** Calls wn_input to perform data entry.
