C--------------------------------------------------------------------------
subroutine ftitab(ounit,rowlen,nrows,nfield,ttype,tbcol,
& tform,tunit,extnam,status)
C insert an ASCII table extension following the current HDU
C ounit i fortran output unit number
C rowlen i width of a row, in characters
C nrows i number of rows in the table
C nfield i number of fields in the table
C ttype c name of each field (array) (optional)
C tform c format of each field (array)
C tunit c units of each field (array) (optional)
C extnam c name of table extension (optional)
C OUTPUT PARAMETERS:
C status i output error status (0=OK)

C END OF COMMON BLOCK DEFINITIONS:------------------------------------
integer ibuff,nhdu,i,savstr,nblock,hsize,nkey
if (status .gt. 0)return
ibuff=bufnum(ounit)
C close the current HDU to make sure END and fill values are written
call ftchdu(ounit,status)
if (status .gt. 0)return
C save the starting address of the next HDU
nhdu=chdu(ibuff)+1
savstr=hdstrt(ibuff,nhdu)
C count number of optional TUNITS keywords to be written
nkey=0
do 5 i=1,nfield
if (tunit(i) .ne. ' ')nkey=nkey+1
5 continue
if (extnam .ne. ' ')nkey=nkey+1
C calc min size of header
nblock=(9 + 3*nfield + nkey +35)/36
hsize=nblock*2880
C define a fake CHDU with minimum header
dtstrt(ibuff)=hdstrt(ibuff,chdu(ibuff))+hsize
C define the size of the new HDU (this modifies hdstrt(ibuff,nhdu))
call ftadef(ounit,rowlen,nfield,tbcol,tform,nrows,status)
C use start of next HDU to calc. how big this new HDU is
nblock=(hdstrt(ibuff,nhdu)-hdstrt(ibuff,nhdu-1))/2880
C reset the start of the next HDU back to it original value
hdstrt(ibuff,nhdu)=savstr
C insert the required number of blocks at the end of the real CHDU
C (first define hdutyp so that the correct fill value will be used)
hdutyp(ibuff)=1
call ftiblk(ounit,nblock,1,status)
if (status .gt. 0)return
C increment the number of HDUs in the file and their starting address
maxhdu(ibuff)=maxhdu(ibuff)+1
do 10 i=maxhdu(ibuff),nhdu,-1
hdstrt(ibuff,i+1)=hdstrt(ibuff,i)
10 continue
C again, reset the start of the next HDU back to it original value
hdstrt(ibuff,nhdu)=savstr
C flush the buffers holding data for the old HDU
call ftflsh(ibuff,status)
C recover common block space containing column descriptors for old HDU
call ftfrcl(ounit,status)
C move to the new (empty) HDU
chdu(ibuff)=nhdu
C set parameters describing an empty header
hdutyp(ibuff)=1
nxthdr(ibuff)=hdstrt(ibuff,nhdu)
hdend(ibuff)= hdstrt(ibuff,nhdu)
dtstrt(ibuff)=hdstrt(ibuff,nhdu)+hsize
C write the header keywords
call ftphtb(ounit,rowlen,nrows,nfield,ttype,tbcol,tform,tunit,
& extnam,status)
C define the structure of the new HDU
call ftadef(ounit,rowlen,nfield,tbcol,tform,nrows,status)
