C--------------------------------------------------------------------------
        subroutine ftgtcl(iunit,colnum,datcod,repeat,width,status)

C       get the datatype of the column, as well as the vector
C       repeat count and (if it is an ASCII character column) the
C       width of a unit string within the column.  This supports the
C       TFORMn = 'rAw' syntax for specifying arrays of substrings.


C       iunit   i  Fortran i/o unit number
C       colnum  i  number of the column (first column = 1)

C       datcod  i  returned datatype code
C       repeat  i  number of elements in the vector column
C       width   i  width of unit string in character columns
C       status  i  returned error status
