18.30  TDTEXT 

Outputs titles
     CALL TDTEXT('options','title','case'[,x[,y[,z]]])
This puts the title at the specified x,y,z

     1.  options  - This is a string specifying the options.  These may be
         any options used by the TITLE command.   Some  available  options
         are:
              TOP, BOTTOM, RIGHT, LEFT, DATA, ANGLE=n, X, Y, Z, SIZE=n
     2.  title - text to put on the screen. 
     3.  case - The case string.  If ' ' is used then the text consists of
         normal ASCII characters
     4.  x,y,z  -  Specify  the  title  position  in TEXT coordinates.  If
         omitted and no options are specified, the current title is placed
         under the last.

This  is  a  Fortran-77  compatible  subroutine.  Do not use %REF with the
option, title, or case strings.  Options, title, and case must  be  either
literals or character variables.
