WAVEFORM BASIC    ver 1.62   vs.  ver 1.9   vs   ver 2.0
---------------------------------------------------------------------------

NEW COMMANDS IN VER 1.9

         Recall$ : Recall a waveform from disk. Takes a string as argument,
                   useful in programs.

          Store$ : Store a waveform to disk.  Takes a string as argument.

           Chdir : Change default directory.




MODIFIED COMMANDS in ver. 1.9

Install (sub),D  : Allows installation of subprograms when Out of Memory.
                   Program resides on disk until called.

          Hplot  : Reads mechanical plotter limits from plotter to ensure
                   proper scaling of plot to page.  Therefore, does not
                   support Centronics plotters.  (Can be simply modified for
                   Centronics use though.)

                   the error handling routine. 
                
            WMAX : Finds the maximum points of two waveforms.

            WMIN : Finds the minimum points of two waveforms.
             



MODIFIED COMMANDS in ver. 2.0

         DOTJOIN : New mode: DOTJOIN ON.  All waveforms plotted on the 
                   screen are dotjoined.  Command DOTJOIN OFF used to 
                   restore screen plots to normal (unjoined) mode.
             
    RECALL A@,31 : Recalls a PC-31 waveform from disk into memory. 
           
    RECALL A@,32 : Recalls a PC-32 waveform from disk into memory. 
                
          XYPLOT : Now allows screeen dump to Epson printer.
   
                
              F5 : Function key F5 is no longer "PLOT", is now "WFMENU"
                   Pressing F5 brings up the menu interface.

             New Product :

             WAVEFORM BASIC APPLICATION PACK
 
             The Application Pack provides a number of additional commands
             for Waveform Basic.  These commands can be used as is
             or customized by the user.  A hard-disk system is required.


   AREA     : Finds area under a waveform, within user defined boundaries.

   BOUND    : Determine whether a waveform exceeds selected boundaries

   FREQ     : Find the difference in frequency between two points of a
              waveform.

   HARMON   : Find the amplitude of harmonics and store in a waveform.

   HARMOND  : Find the amplitude of harmonics and display the result.

   HLOG     : Create a horizontal Log display of a waveform.

   HSHIFT   : Move a waveform horizontally.

   LINFIT   : Finds a line which is the least-squares fit of a waveform.

   LOGLOG   : Create a Log-Log display of a waveform.

   PARFIT   : Finds a second-order polynomial which is the least-squares
              fit of a waveform.

   PCOUNT   : Count the peak points of a waveform

   PEAK     : Detect and store the peak points of a waveform

   RENUM    : Renumber program lines.

   STANDEV  : Finds the standard deviation of a waveform.

   SUM      : Sums the amplitude of each point in a waveform.

   VALLEY   : Detect and store the valley points of a waveform.

   VARIANCE : Finds the variance of a waveform.

   VCOUNT   : Count the valley points of a waveform


              Model 42 Function Generator

   TERM42   : Causes the computer to act like a terminal so
              I/O commands can be directly executed.

   WRITE42  : Writes a command to the 42.

   ASK42    : Interrogates the 42.

   OUT42    : Loads a waveform (ie A@) into the 42.



              Digital Plots

   CURPLOT  : Plot a waveform along with labeled points.

   HISTPLOT : Plots a waveform as a histogram.

   MULTPLOT : Plots up to four waveforms on a single grid.

   TEXTPLOT : Plots a waveform along with text.

   TWOPLOT  : Plots two waveform grids on a single page.

   XYHPLOT  : Plots one waveform as a function of another.


  
                Filters

     BANDPASS : Removes from a waveform all frequency components not
                between the pre-defined frequency limits.

     BANDREJ  : Removes from a waveform all frequency components
                between the pre-defined frequency limits

     FILTER   : Use the cursor to define cutoff frequencies before filtering

     HIPASS   : Removes from a waveform all frequency components below
                the pre-defined frequency limit.

     LOWPASS  : Removes from a waveform all frequency components above a
                pre-defined frequency limit.
